A lot of bugs and exploits from MOH:AA were fixed in OpenMoHAA (BOF exploit, grenade crash bug, command overflow...).

Summary

  • SDL2 backend
  • OpenAL sound support (better sound quality)
  • Full 64-bit support
  • Cross-platform support
  • Multiuser support on OS (On Windows, user game data is stored in "%APPDATA%\openmohaa")
  • Many bug fixes and additions from ioquake3
  • Automatic scaling of UI elements on high resolutions like 4K

Overall, better compatibility on modern systems and bugfixes.

Additions

General

  • Demo recording
  • Features from ioquake3
  • Features from MOH: Spearhead 2.15 and MOH: Breakthrough 2.40
  • IPv6 support (from ioquake3)
  • Multiple master servers for the serverlist (using 333networks)

Client-side

  • 4K support
  • Customizable FOV
  • Improved mouse support on windowed mode
  • OpenAL and SDL are used
  • Smoother animations

Stufftext restriction

Servers can no longer make players run any command. Only a small number of safe commands are now allowed. This change helps prevent abuse, like unbinding player controls, and improves overall security.

stufftext is now limited to trusted, commonly used commands, like those for controlling in-game music. The full list can be found in cgame/cg_servercmds_filter.cpp.

Server-side

  • Bots
  • IP ban (from ioquake3)
  • More script commands for mods
  • Non-PVS optimization
  • Packet flood protection
  • Print client number and IP for each action
  • Text chat management (enable/disable, configurable delay between messages)

Non-PVS optimization

For each client, the server optimizes by only sending them information about other players that they can see. Clients won't see other players they can't see.

Enable this feature with set sv_netoptimize 2.
