MW2 Recompiled

Modern Warfare 2, recompiled

Call of Duty: Modern Warfare 2 (2009) for the Xbox 360, running natively on PC. Not an emulator: the game's executables are recompiled ahead of time. No game files are included; you need your own disc.

Download the latest release

Features

• Campaign and multiplayer
• Private matches and system link, online with friends:
  • Steam build: invite friends through Steam, no port to open
  • LAN build: for players without Steam, on the same network
• 60 fps, native MSAA, any window size or fullscreen
• Xbox 360-style controller, with rumble

Not supported: public matchmaking and ranked playlists (they needed Activision's servers). Special Ops is untested.

Requirements

• An ISO of the Xbox 360 disc, version 1.0.557 (as on the main menu; title

  updates can't be used). The installer checks it.

• Linux or Windows, 64-bit
• A Vulkan 1.2 GPU
• 8 GB of disk space
• A controller (the keyboard only covers the menus)

Install

1. Download steam or lan for your system from the

   releases, and extract it anywhere.

2. Start mw2-sp (campaign) or mw2-mp (multiplayer). The first time, it

   asks for your ISO and copies the game files into game/ beside it.

From a terminal: ./mw2-mp --install path/to/game.iso (an extracted disc folder works too).

Saves go in saves/ beside the executables.

Play

Online. Everyone runs mw2-mp from the same build.

• Steam: Steam must be running; the game shows as Spacewar. Host a

  PLAY ONLINE → PRIVATE MATCH, invite from Steam's friend list (or F6 if you added mw2-mp to Steam as a non-Steam game). The friend accepts while their game is running.

• LAN: SYSTEM LINK finds games on the network by itself. For private

  matches, the lobby's "Invite friends" invites everyone on the network; start the others with MW2_LAN_ACCEPT=1. Your name is your login, or MW2_NAME=.

Settings (environment variables): MW2_FULLSCREEN=1, MW2_MSAA= or MW2_NO_MSAA=1, MW2_NO_AUDIO=1.

Bug reports: run with MW2_LOG_FILE=mw2.log and attach the file.
