There are some extra things we would like to implement that we may not have time for. We would like to add network play for the PC version of the game, specifically server play (R-EX-1). Doing Xbox Live play for the Xbox 360 version is desirable but there is no support for it in XNA yet. Another feature that we would like to implement is the ability to load your own 3D models for the player characters (R-EX-2). We would also like to include the ability to load your own texture for the terrain or sky (R-EX-3). These features will most likely not be in the final game but are things we would like to do if we have time.
