* Full compatibility with Descent and Descent 2, including all expansions and third-party levels.
* DXX-Rebirth runs on your favourite Operating System. We officially support Linux (and other *NIXs), Mac OS X and Windows. The source code can also be compiled on many other systems!
* OpenGL provides fast and smooth rendering - even on low-end systems.
* Optionally you can enable several effects like Transparency, Colored Lighting, Texture Filtering, FSAA, etc.
* Thanks to SDL, a wide variety of Joysticks are supported. Also you can use more Joysticks, buttons and axes than you can ever operate in your state of evolution.
* Multiplayer via UDP protocol provides a fast and easy-to-use LAN and Online action. This includes reliable communication causing less glitches due to lost packets.
* The ingame Demo-recording system has been improved. Demos are less glitchy and smaller while still still being backwards-compatible to earlier versions of the games.
* Higher game speed will not cause glitches such as unacceptable fast homing projectiles, incredible high damage caused by several collisions or Fusion cannon, etc.
* Player files, Savegames, Demos and Missions from DOS-Versions of the games can freely be used in DXX-Rebirth and vice versa.
DXX-Rebirth supports Multiplayer over UDP/IP.Using UDP/IP works over LAN and Internet.
By default, each game communicates over UDP-Port 42424. This can be changed via the menus, command-line argument or .ini files.
Please be aware that if you host a game and players want to join your game online via direct IP connection, your specified game port should be forwarded on your router.
If you host your game on the Online Tracker and other players join via this method, port forwarding should not be necessary.
If you only want to join a game, or host a game on LAN (not online), port forwarding should not be necessary. If you do experience problems, please check your NAT settings and/or Firewall.
