The robot fighting classic, rebuilt

Ninety-foot war machines.
One must fall.

In One Must Fall 2097 (Diversions Entertainment, 1994), pilots climb into giant robots and fight their way up a corporate tournament. It was one of the great DOS fighting games, and it has been freeware since 1999.

This project brings it back: a faithful reimplementation of the game's engine that plays the original game files, as a free app for Windows, macOS and Linux or in a browser. Play it exactly as it looked in 1994, or remastered in HD with new effects, modes and tools.

  • Faithful

    Every robot, arena, mode and quirk of the original, following the reverse engineering of OpenOMF. The soundtrack plays through a port of the game's own music driver.

  • Remastered

    3,200+ images redrawn in HD, widescreen arenas with depth, dynamic light and particles, smooth motion, and sharp text at any resolution.

  • Modern

    LAN games, fourteen languages, a training lab, replays and clips, new modes, a robot workshop, mods and OMF Studio, gamepads with rumble, touch controls. It even works offline.

The same moment, both ways. switches at any time, even mid-fight. Try it here.

Classic

  • The original VGA picture, rebuilt on the GPU: 320 × 200 pixels through the game's palette and its 19 color tables, exactly like 1994
  • Sharp pixels, smooth scaling or a CRT filter
  • Widescreen fights if you want them

Remastered

  • HD artwork for every arena, robot, portrait and effect, and an edge-aware upscaler for anything else
  • Player colors, fades and flashes still work: they are mapped onto the HD pixels live
  • Widescreen arenas whose paintings have depth: the camera gives them parallax, and light falls by shape
  • Smooth motion between game ticks, bloom, a crisp HUD and a sharp typeface fitted to the original fonts

02 The whole 1994 game

The 1994 roster · 11 robots

Jaguar, in its factory paint

All-rounder

Jaguar

The robot most pilots learn on, and the one many never leave. Quick on its feet and quicker to punish: it leaps across the arena, fires a concussion cannon and throws opponents clean over its head.

Special moves

  • Jaguar Leap
  • Concussion Cannon
  • Overhead Throw

The W.A.R. circuit

The pilots

Each brings a body and a mind to the neural link: their power, agility and endurance shape every robot they pilot, and the computer plays each with their own personality.

Five arenas, five hazards

The arenas

Painted again in HD and opened up to widescreen: the Danger Room's spikes, the Power Plant's fences, the Fire Pit's fireballs and the Desert's strafing jets are all still here.

  • Stadium: the arena's HD painting

    Stadium

    Where W.A.R.'s machines get their first public testing: a steel pit under floodlights, the crowd behind the cage net.

  • Danger Room: the arena's HD painting

    Danger Room

    Spikes shoot out of the walls. Keep your opponent against them, and yourself away from them.

    Wall spikes

  • Power Plant: the arena's HD painting

    Power Plant

    Built inside a lightning-receptive power plant: the walls deliver electric shocks.

    Electrified fences

  • Fire Pit: the arena's HD painting

    Fire Pit

    Holographic spheres ignite fireballs under the fighters, over a grate of glowing lava.

    Fireballs

  • The Desert: the arena's HD painting

    The Desert

    Golden dunes at sunset, and fighter jets strafing anything that stands still.

    Strafing jets

Something lives under the Fire Pit

Fire and Ice

The one-player game's two secret opponents, as the 1994 program hides them. On Champion or harder, a destruction in the Fire Pit, then your robot's Fire & Ice move, sends it through the floor to fight Fire, an enhanced Katana in the burning pit below. On Ultimate, the same against Fire leads on to Ice, a translucent Shadow in a frozen pit.

One and two players, the demo, the full tournament career with the mech lab, upgrades, training and the newsroom, the scoreboard, the intro and every ending. The menus were tidied up without losing anything, and a few things the 1994 menus promised finally work.

03 Fight effects

Sparks, light, shockwaves

Remastered fights get a layer of modern effects, driven by what happens in the fight.

  • Fire Pit

    Rising embers, torchlight on the robots, heat haze over the grate.

  • The Desert

    The sunset behind the robots, sun shafts, sand blowing over the dunes.

  • Power Plant

    The electrified fences throw blue light across the arena.

  • Knockouts

    A flash, a shockwave, sparks and a slow-motion zoom on the final blow.

  • ParticlesSparks and flares on hits and blocks, dust from falls, throws and wall slams
  • LightingHits, fire, energy and projectiles light up the arena and the robots
  • ImpactShockwaves on heavy hits, and the knockout camera
  • AtmosphereEmbers, sand, floodlights, camera flashes; snow, aurora, rain and neon in the new arenas

The effects are only for the eyes. They never touch the game's state or its random numbers, so a fight plays out exactly the same with them on or off (a test checks it). Each group can be turned off in Options › Graphics › Effects.

04 New ways to play

More than 1994 ever had

All of this is new, and none of it changes how the original plays unless you use it.

Training lab

A dummy that never goes down, and the tools of modern fighting games: frame data and pixel-exact hitboxes, record the dummy and play it back, answer with a reversal, and combo trials for every robot, found by searching the game itself.

In your language

Fourteen languages, the 1994 texts and everything new, drawn in the original pixel font where its letters reach.

LAN multiplayer

Fight a friend on another computer of your home network, on any of the three systems. Both play the very same fight, tick for tick, and only tell each other what was pressed.

Watching a replay: the playback bar with its timeline and a marked clip

Replays and clips

Every fight is saved. Watch at any speed, step frame by frame, and save a clip as an MP4 or a GIF.

Arcade, survival, time attack

  • Arcade eight fights, Kreissack last
  • Survival round after round, on the health you have left
  • Time attack five fights against the clock

Records and 20 achievements, with nothing locked behind them.

Robot workshop

Build your own robot from the new robots' parts: one's frame, another's head, a third one's special moves, a size, a weight and three colors. It becomes a full fighter on the spot, shared as a small .omfbot file.

The credits are fought out

Scored to Twenty Ninety-Seven (Remix) by Hadal Static: each credit pilots a robot against something the remaster had to beat (tech debt, spaghetti code, pixel noise) and wins on the beat.

Your own tournaments

Fewer opponents, their robots as they were or the new ones, more or less prize money. They show up in Tournament play, shared as .omftrn files.

Two announcers

Victor and Kristen call the rounds, the knockouts and the winners, and after a fight a newsreader reads the TV report aloud, names and all.

A victory screen: the winner's portrait, robot, a line of theirs and the fight's numbers

Victory screens

The winner, a line of theirs, and the fight in numbers. And a fight camera, if you want it.

  • Xbox and standard gamepads, with rumble
  • Modern layouts and one-button specials
  • Touch controls on phones and tablets
  • Your own music, dropped onto the window

05 New robots and arenas

New challengers

Four robots and four arenas made for the remaster, in the spirit of the originals. The 1994 game stays as it was: they come with it as a mod, off until you turn on New robots and arenas in Extras › Mods.

The new robots on the VS screen: GLACIER against TEMPEST, HELIX against SPECTRE

They play like the originals: the full set of moves, a throw, a scrap and a destruction finisher, the player's three colors, and a computer that knows how to fight with them. Pick them from the robot select above, or see their moves in the manual. Their HD frames are rendered in Blender from the remaster's own 3D models.

  • Orbital: the arena's HD painting

    Orbital New

    A space station's hangar with the Earth in its window. Dust floats in the low gravity, and now and then a shuttle passes outside.

  • Ice Cave: the arena's HD painting

    Ice Cave New

    A frozen cavern under the aurora. Snow blows in, frost mist creeps over the ice, shooting stars fall over the mountains.

  • Rooftop: the arena's HD painting

    Rooftop New

    A skyscraper's roof in the rain above a neon city. Lightning flashes over the skyline as a hover-car cruises by.

  • Abyss: the arena's HD painting

    Abyss New

    A glass dome on the sea floor. Bubbles rise, light ripples over the floor, a submersible glides past.

06 Mods and OMF Studio

Make your own

Mods add robots, arenas and pilots that play exactly like the game's own, in both looks, in every mode and in replays. OMF Studio makes them, in the game's own formats, pixel for pixel.

  • Robots from a copy, the workshop's parts or a blank figure: every frame, hit point, input and reaction
  • Arenas from a copy or a picture, with hazards, scenery and music
  • Pilots: portraits, lines, a personality for the computer, an ending
  • HD artwork: templates to paint over, or renders of a robot's 3D model
  • Test in the game straight from Studio, then build the .omfmod to share
