Legacy of Rust


Legacy of Rust | ID1.WAD

 id Software, Nightdive Studios, MachineGames

In these uncertain times there's a certain comfort in nostalgia. Going back to old favorites, or discovering a classic for a new generation, either way it's something to remind us of simpler times. The classics of yesteryear have been, one by one, getting new life, in part through the Herculean efforts of Nightdive Studios. Quake and Quake II, Blood, Rise of the Triad -- all resurrected for modern audiences. And then, during Quakecon 2024, Nightdive hit us again, this time with Doom + Doom II, a remastered port of classic Doom -- including Final Doom and expansions -- in a new configuration of Samuel "Kaiser" Villarreal's KEX engine, modeled off of a fork of Chocolate Doom. But hark! What's this? A brand new expansion, utilizing the many bits and pieces left behind on the cutting room floor during Doom's development? With the mapping talents of Villarreal and Xaser Acheron, among others? And utilizing a new standard based on MBF21? Say it ain't so! Welcome to Legacy of Rust

Legacy of Rust positions itself sometime after Doom II, exactly when is unclear, as is who the protagonist is supposed to be -- Doomguy? Or someone else? (For my own amusement I used the female skin for skelegant's excellent One Hell of a Marine MBF21 mod.) The UAC has committed one of its most boneheaded moves yet: it has literally colonized Hell itself, and things have naturally gone terribly awry. They had intentionally built in a remote corner of this evil dimension, far away from all the ghosts and goblins that roam the wastes, but it never occurred to the UAC to wonder why Hell's denizens avoided the place called Vassago's Rest, renamed New Eden by the UAC in a fit of incredible hubris. And then the vassagos showed up. Your job -- whoever you may be -- is to break into the abandoned facility, fight your way to the nuclear missile stockpile, and set them to self-destruct, presumably to keep Hell's denizens from getting hold of whatever technology the UAC's built down there.

Legacy of Rust is split into two episodes of eight maps each, with one secret level per episode. The vast majority of the episode was built by Villarreal and Xaser, both of them in their capacity as employees of Nightdive. For a couple of maps, we also get the mapping talents of Ethan "Gooberman" Watson, a Nightdive contractor whose work on the Rum n' Raisin source port -- itself a fork of Chocolate -- was instrumental in the development of Doom + Doom II, the awkwardly-named source port that powers the remaster. (DDII, for its part, does something no official port has yet done: include support for popular mapping standards Boom, MBF, and MBF21, while introducing the new ID24 standard off the back of MBF21. While the exact implementation of this wasn't received with universal praise, I think ultimately all that drama turned out to be a nothingburger as ID24 has been pretty much ignored by everyone and the terrifying prospect of a corporate takeover of the community never materialized. The haphazard launch of the mod uploading tool was definitely the much bigger controversy and not without good reason.) And finally, we get one map each by Thomas Carter and Kevin Dunlop, who are both senior environment artists at MachineGames and id Software, respectively. Their maps in particular are marked by two things: a new, cohesive texture scheme that really pops, and being linear to a fault. Ah well.

New episodes for old games is nothing new; Duke Nukem 3D infamously got the band back together for the 20th anniversary, and even Doom II got a new episode in Nerve Software's No Rest for the Living a long while back. But Legacy of Rust is more than that, it's a celebration of Doom's history. A large part of the wad's appeal is its resurrection of long-forgotten assets that were cut from the final game, ranging from textures in the style of the Doom development alphas to whole new enemies and even weapons using forgotten art. First, the weapons: most of your gear is the same, but the energy weapons have been replaced with a flamethrower with limited range but its flames do AOE damage over time, and the Calamity Blade, a goofy-looking weapon of mass destruction (its sprites frankensteined out of the same toy gun that formed the BFG 9000) that fires a wave of flames that do tremendous damage and can mow down hordes of low-level enemies in a single shot. I suspect these weapons were Xaser's idea, given his affection for weapon mods. The enemy roster is much the same but there are some new additions, the first being the ghoul, a flying horned skull based on an old version of the lost soul, that shoots fireballs at you but withers under shotgun fire. Next you get the shocktrooper, an undead marine with a plasma rifle, because fighting these guys in Scythe 2 wasn't enough. The mindweaver is an arachnotron with its mommy's chaingun, making it a threat that is simultaneously weak and dangerous. The tyrant is a hornless, weaker version of the cyberdemon, appearing only in the final map. Banshees are my favorite new addition, as they introduce an entirely new aspect to the gameplay: screaming red flaming faces that charge you and explode. And lastly there's the vassago, a big, ugly bastard that looks like a skeletal, flaming take on the hell nobles and behaves much the same, except his fireballs leave flames with their own AOE damage!

In spite of its nods to Doom's alpha era, at its core, Legacy of Rust is a product of the modern Doom community, warts and all. If you're like me and most of your formative Doom memories are in mapsets like The Darkening Episode 2, Phobos: Anomaly Reborn, Caverns of Darkness, Icarus: Alien Vanguard, and Mordeth, or perhaps you're new to the series entirely and haven't played anything beyond Final Doom, then Legacy of Rust is going to seem a little overdone. From the opening moments in "Scar Base" all the way to the final insanity that is "Brink," Legacy of Rust doesn't pull very many punches, especially if you're playing on higher difficulties. "The Coiled City" -- Xaser's masterpiece for this set, in my opinion -- will run you raw if you're unprepared, and quite often you'll be thrown into close quarters to face a horde of enemies. This culminates, of course, in the one-two punch of "Soul Silo," a series of increasingly unruly slaughter spectacles, and "Brink," which starts off tricky and quickly descends into borderline unwinnable. There's a lot to be said here about the direction the community has taken in the years since Hell Revealed II; sometimes I look at the kind of stuff that makes the rounds these days like NEVER or Sunder or even Mudman and I hardly recognize Doom in it. Legacy of Rust is absolutely a part of this trend, and that's probably going to be a turn-off for some people. Part of the problem, of course, is that the community is thirty years old and long-timers are looking for more challenge, and that's totally understandable. But -- and I'm saying this as a big fan of No Rest for the Living, which was certainly no slouch in the Plutoniousity department -- maybe this kind of stuff shouldn't be public-facing. Maybe we shouldn't be using Plutonia, or worse, Hell Revealed II, as the skill floor for a new episode to entice normies who haven't played anything beyond the stock maps, if at all. Imagine trying to play Villarreal's Lost Episodes expansion for Doom 64 on the old Nintendo 64 controller.

This isn't to say that I don't like Legacy of Rust. I do -- at least, on paper. In practice, it took me way too long to finish it, with a couple of long breaks, because I find the set to be something of a chore. It's not that I don't love hard wads -- in fact, during the last long break, I went through some pretty tough wads like Preacher and MAYhem 2019. There's just something about Legacy of Rust that leaves me cold. Thematically it's all over the place; even leaving aside the beautiful texturing jobs on "Spirit Drains" and "Soul Silo" clashing with the rest of the wad's use of vanilla-style assets, the whole hellbase thing is inconsistent and composed of a variety of different ideas and design tropes that don't always gel together. I would rather they had done something more thematically consistent -- there was always room in the alpha stuff for Doomcute offices and stuff, or at the very least why not have just gone all-in on the modernist texture aesthetics? The new monsters as a rule don't typically add very much to the experience except for the banshees, and the new weapons are generally underwhelming when I really needed them to count.

In the end, though, Legacy of Rust is what it is: an artifact of a community that's long been left to its own devices; at best, it's an attempt to legitimize thirty years of development and community growth, at worst it's a corporate intrusion into a notoriously open-source, fair use-minded community. Ultimately, what it tried to bring to the table has been generally ignored; ID24 mapping did not materialize overnight, and even most source ports don't fully support the standard yet. Far from being an exciting new entry in the commercial Doom canon, Legacy of Rust has been left behind, more rust than legacy. 


Episode 1: The Vulcan Abyss

MAP01: Scar Base

Samuel "Kaiser" Villarreal

A quick n' clean little techbase intro, mostly silver in color and split in two sections divided by a tunnel. It's a cool level with office chairs and workstations, making good use of the old alpha assets. The best part is the Stargate-esque portal that leads to the UAC's outpost in Hell -- turn it on and a bunch of the new beta lost souls (known here as "ghouls") come out to hassle you.

MAP02: Sanguine Wastes

Xaser Acheron

The opening level was just a taste; this is a heaping spoonful of hellish action. From the swarms of imps and other nasties coming out of nests in the rock, to the massive fight for the rocket launcher in the blood lake at the foot of the dam(n), to the messy run-and-gunning in the main building as you try to line pipes up for a pathway to the roof exit, to the explosive introduction to banshees, it's an impressive map with lots of fun secrets to find.

MAP15: Ash Mill

Xaser Acheron

A short, but spooky little map that has you exploring an abandoned mill. What this mill actually makes is unclear, but it's certainly not paper. It's seemingly unoccupied until you get the red key, at which point a squad of shocktroopers carrying plasma rifles come to kill you. That first encounter is delicious, the way it's set up so you don't immediately recognize him as a threat until you enter the room he's in.

MAP03: Spirit Drains

Thomas Carter

There's a lot of different kinds of maps. There's the relatively short rides that the stock Doom 1 maps provide; there's the nasty little puzzle boxes like we get from Plutonia or SIGIL. There's the big, beautiful maps full of slaughter. And then there's maps like this -- a lengthy, winding journey that twists in on itself like a nest of snakes. It's appropriate that a MachineGames dev be behind this level, given its starkly Quake (both 1 and II)-ish industrial vibes, enhanced greatly by a new texture set. Carter mostly throws hordes of trash mobs at you, with plenty of revenants for spice. He also likes to make use of arch-viles at key moments. But it's the final fight that is the level's centerpiece, in which Carter introduces us to the vassago, a hulking cousin to the hell nobles who throws fireballs with lingering flames. Firing off a shot triggers a large invasion of bad guys including a couple of archies, and it's arguably safer to grab the blue key when you have an opening and get out.

MAP04: Descending Inferno

Samuel Villareal

A nice little techbase in a volcanic region of Hell, you'll have plenty of indoor/outdoor action. Mind you don't get hot feet as you work your way around the lava rivers. Vassagos show up, so do shocktroopers, and so do mindweavers, nasty little mini-masterminds who take about as much damage as the baby arachnotrons but dish out a big momma's worth of pain with their personal chaingun. The map weaves in on itself in interesting ways, mostly on the western side.

MAP05: Creeping Hate

Samuel Villarreal

Complete with a parody of "The Only Thing They Fear Is You," the Kaiser drops a hell factory on us with moving conveyor belts and control boards and lots of lava to fall into. It's mostly pretty straightforward, though Sam likes to unleash big ambushes. I like how the stuff at the end of the lava hallway is tantalizing but you can't actually get there until you get the blue key, which is a whole 'nother quest.

MAP06: The Coiled City

Xaser Acheron

This is one of the big setpiece levels of Legacy of Rust. Xaser, God bless 'im, gives us a weird, winding nightmare suspended over a lava sea. Vassagos and shock troopers are the primary threat here, with broad lines of fire making pretty much most of the map unsafe to linger at. Ghouls and banshees get strategic releases here and there to drive you to distraction, and the opening salvo -- a mindweaver ambush -- sets the tone for the rest of the map after a lengthy, monsterless intro. The big gimmick (besides the dark tunnels that defy rational physics and aren't on the map) is that other than a cleverly-hidden stash of rockets, the only ammunition in this map is fuel, forcing you to rely on your incinerator (and a Calamity Blade, if you're clever enough to find it!) Almost all the enemies are the Legacy of Rust exclusives, too -- there might be the odd arch-vile and imp but that's about it. Not everyone likes this map, but I think it's great -- it feels like something from the latter half of Plutonia 2, but slightly different.

MAP07: Forfeited Salvation

Samuel Villarreal

The Kaiser gives us a relatively straightforward death box, devoid of any signs of being a former base. A cyberdemon hangs out in the middle with a few shocktroopers providing overwatch. On either side are different wings of the map you'll need to clear out. Your job is to find your way to various switches that raise and lower walkways so you can access the red key the cyberdemon is guarding, and from there clear out the bullshit in the wings. It doesn't quite feel quite as Kaiser-ish as some -- he tends to make more interconnected mazes. But it does feel almost Doom 64-ish... at least until it drops you into a pit with some vassagos, who tear you apart with abandon. Feels familiar...

Counterfeit Eden

MAP08: Second Coming

Ethan "GooberMan" Watson & Xaser Acheron

From Xaser and Ethan "GooberMan" Watson (who also played a big role in the development of the KEX Doom port) comes this rough little opener. While there are a few remnants of the area's techbase past, it's hard to see past the hellish corruption, with walkways collapsed and courtyards full of lava or blood. You'll be short on firepower for most of the map, with tougher enemies like vassagos making themselves known pretty early on, and at one point a cyberdemon warps in to stand watch over the western courtyard, making things even more dangerous. But if you're secret-savvy you can get your hands on a berserk pack to help.

MAP09: Falsehood

Samuel Villarreal

A somewhat industrialized hell ruin amidst a rocky canyon. The action is generally about medium pressure, with no terribly large squads of baddies to ruin your day. Kaiser doesn't always rely on punishing the player for progress either -- keys are rewards, not traps. Your main threat is probably going to be the clouds of ghouls and their pain elemental chaperones filling the skies, but Kaiser also makes careful use of vassagos to turn up the heat in certain encounters. Like a lot of Legacy of Rust maps it's a bit of a journey, but it's a fun one that eventually has you returning back where you started. Love the exit fakeout.

MAP10: Dis Union

Ethan Watson

The GooberMan crafts a nasty little monster nest out of what by now should be a familiar aesthetic, that of a corrupted hellbase. Most encounters aren't too rough provided you're prepared, but the lobby rush early on -- made worse when the doors re-open letting in the skelly bois -- throws a lot of meat at you in close quarters. There's also the revenant/chaingunner fight, even more telegraphed than the lobby battle, but by this point you probably won't have a lot of armor and it can get dicey in a hurry. The toughest fight by far, however, is the red key room, where you must fight a horde of fliers in a large room as the floor gradually sinks.

MAP16: Panopticon

Xaser Acheron

Oh god, a puzzle map. A panopticon in the original sense was a design for an ideal prison by 18th-century Utilitarianist philosopher Jeremy Bentham in which a central guard tower could keep an eye on prison cells arranged in a circle around it, thereby removing any expectation of privacy on the part of the prisoner's. This map works on a similar principle: 20 monsters and you'll feel most of them, because that cyberdemon lording over the whole level from the central platform will ruin your day again and again. Basically you have to dodge its rockets while working your way through a gauntlet of bullshit, including a damaging blood maze, damaging stairs, and a switch puzzle where you have to run to a switch in between rocket volleys then run back to cover. On the plus side, you finally get the backpack and Calamity Blade for your efforts.

MAP11: Echoes of Pain

Samuel Villarreal

Real strong The Darkening Episode 1 vibes from this map... it's a mostly brownbase affair with a touch of Satanic decoration for spice. In spite of being a late-game Kaiser map it's pretty easy, with the most exciting encounter being a cacodemon swarm in the north once you've grabbed the blue key. I liked the weird grey cell block thingie in the southeast with the chaingunners, fun encounter there.

MAP12: The Rack

Samuel Villarreal

The Kaiser looked upon the tortured expanses of "Counterfeit Eden," and proclaimed thus: "This needs more Episode 4 in it." And so he created "The Rack," and when he was finished, he looked upon his work, and saw that it was good. Don't let the 300+ monster count fool you, this is actually a fairly sedate adventure for the most part. The core of the map is a large four-sectioned open space bisected by walkways; each quadrant has its own features, and the trick of the map is finding your way to the spaces beyond. Thematically it's all over Doom's infamous fourth episode -- you got your blood pools, you got your green marble, you got your wood and metal, you got eldritch temples and forgotten promenades. Expect to see lots of banshees here, Kaiser unleashing them on cue to throw a little spice into the proceedings.

MAP13: Soul Silo

Kevin Dunlop

Nice texture scheme, very Doom 3. Kevin Dunlop brings us a brutal penultimate map that has us traveling through a linearly-designed underground nukage plant; each new room brings a dangerous crush of enemies, with just enough flamer ammo to chew through it and occasionally the need to figure out a safe zone to do most of the shooting from. Very Ribbiks-esque, if you ask me. A brief trip into a Satanic marble garden will let you really test out the power of the Calamity Blade as it mows down hundreds of imps. I really like the visuals in most of this map, especially the elevator to the final chamber.

MAP14: Brink

Xaser Acheron

Come on Xaser, what the fuck is this? The opening is suitably atmospheric as you approach the subverted nuclear launch facility. The first couple of encounters aren't too bad -- Xaser throws a cybie and a few of his little brothers, the tyrants, at you. Get them fighting and they'll be too busy to notice you throwing switches. The maze fight -- with vassagos wandering around -- is made only slightly spicy by the addition of archies when you grab one of the keys. But then you get upstairs and all bets are off. On higher difficulties this is borderline impossible -- Xaser throws an enormous horde of vassagos at you (manageable) and arch-viles (fuck off.) You're supposed to use the Calamity Blade to deal with it, but it's just not good enough to mow through these dumb bastards before they roast you to a crisp. Get through all that and you'll face a horde of tyrants in relatively tight quarters. I really like this map on paper but in execution this is just trolling.

Winds blow from the bowels of Hell
Will we give warning? Only time will tell
Satan rears his ugly head
To spit into the wind
