Just like to say a few things if you haven't played this:
  • Sauberbraten is made on the Cube2 engine.
  • This engine is fully customizable
  • Allows in-game level editing ( Multiplayer level editing :o )
  • Is a very UT / Quake game
  • Epic
  • Did I mention the in-game level editing?
I would post pictures of my current WIP map , but unfortunately filesmelt isn't working for me at the moment.
