Modifications
XWA is the only one of the X-wing series to have no expansion or enhanced remake. LucasArts did release a patch that, among other things, adds a flight camera to the game.
The game is modifiable; fans and programmers have created improved textures and models for the ships, new missions, and other modifications. Some modifications are remakes of missions from previous games in the series.
