DX RUST

DX RUST

The original Deus Ex, rebuilt in Rust on the Bevy engine and played with your own copy of the game.

DX RUST is a from-scratch reimplementation of Deus Ex (Ion Storm, 2000). It reads the game's own maps, textures, sounds, music, conversations and class defaults straight from your install, and reproduces the original's gameplay one-to-one:

• every mission, the three endings and the credits;
• AI, combat, stealth, skills, augmentations, inventory;
• conversations, infolinks, computers, keypads;
• saves and the original menus and HUD.

It runs as a native Windows program and on Steam Deck / Linux, with no old engine underneath.

You need your own copy of Deus Ex (Game of the Year Edition from Steam or GOG). No game files are included here or in the releases.

Features

• The whole game. All 73 maps, every mission script, scripted set pieces and both training courses. Travel between maps keeps the state of hub maps, and the next map is read ahead.

• Faithful by default. The original rules, numbers and quirks, checked against the original scripts. Every modern change is an optional switch in Settings > Enhancements.

• Modern engine underneath.

  • A fixed-timestep simulation, so play is the same at any frame rate.
  • Resolution-independent, crisp UI.
  • No sound-channel limits.
  • Fast loading.

• Controller support.

  • Full gamepad play, with modern-shooter defaults that you can remap.
  • A radial aug wheel and D-pad aug pages.
  • Xbox and PlayStation button glyphs, and snap-to navigation in the menus.

• DualSense. Health on the light bar, adaptive triggers for each weapon class, and rumble. Over USB, also HD haptics and infolinks through the pad's speaker.

• Lay D Denton Project support. Play as the female JC with the community mod's voice, looks and conversations. Point the launcher at the mod's folder (see below).

• Smooth lip sync. Mouths blend between sounds and close gently, and people blink visibly. The timings follow Joe Wintergreen's lipsync mod, and there's a switch in Enhancements to turn it off.

• Optional extras:

  • dialogue hotkeys and Discord Rich Presence;
  • inventory auto-sort;
  • keypad codes and logins taken from your notes;
  • using consumables straight from the floor;
  • ladder grabbing;
  • enemies that run out of ammo;
  • casings and blood that stay;
  • a debug menu with the original cheats.

  Every setting, the original ones included, is on one searchable list.

• Rotating autosaves on map changes and completed goals.

Getting started

Windows

1. Install Deus Ex (Steam or GOG).
2. Download dxrust-windows.zip from Releases and unzip it anywhere.
3. Run dxlauncher.exe. It looks for the Deus Ex folder on its own; if it can't find it, click Game Folder....
4. Choose a display mode and resolution, then click Play.

Steam Deck / Linux

1. Install Deus Ex: Game of the Year Edition through Steam. Proton installs the files DX RUST needs, and you don't have to run the game.
2. In Desktop Mode, download dxrust-steamdeck.tar.xz from Releases and extract it, for example to ~/Games/dxrust.
3. Run dxlauncher once to check that it found your game. Steam libraries and SD cards are searched automatically.
4. Add dxrust.sh (or dxlauncher) to Steam as a Non-Steam Game to play from Game Mode. Use Steam Input's Gamepad template.

Lay D Denton (optional)

1. Download the Lay D Denton Project and unzip it.
2. In the launcher, click Lay D Denton... and choose the mod's folder. Right-click it to turn it off again.
3. Start a new game and use the portrait arrows. Every other face is the female JC. Tick Original Morpheus? or Original Interactions? if you want the original versions of those.

The mod's files stay in their own folder: nothing in your Deus Ex install is changed.

Building from source

You need Rust (stable) and, on Windows, the Visual Studio C++ build tools.

cargo build --release -p dxview                                       # the game
cargo build --release --manifest-path crates/dxlauncher/Cargo.toml    # the launcher
target/release/dxview "C:\path\to\Deus Ex"                            # or run the launcher

On Windows, BUILD_RELEASE.bat makes a shareable dist\ folder.

Crate	What it does
unreal-pkg	Reads Unreal Engine 1 packages: names, exports, properties, textures, sounds, meshes, class defaults, mod folders
dx-level	Builds a map: BSP geometry, lightmaps, collision, actors, navigation, conversations
imsim-core	Engine-neutral rules: movement physics, flags, inventory, skills
imsim-audio	A software mixer: positional sounds and tracker music with section jumps
dxview	The game itself, on Bevy
dxlauncher	The launcher (egui)
dxtool	Command-line package inspector

Status and what's left

The whole game is implemented. Before 1.0:

• a full playthrough, with fixes for whatever it finds;
• tuning by eye (water, a few intro effects);
• a performance pass;
• Steam Deck tuning;
• save round-trip tests on every map.

After 1.0, the v2.0 list: HUD customisation, smarter stealth, perks, new effects, real-time shadows, HD asset support and multiplayer, among others. Every item stays optional.

The full list is in ROADMAP.md. Bug reports from playthroughs are very welcome: say which map you were on and what you did.
