The objective of the Killer App Mod for TRON 2.0 on the PC, is to incorporate elements from TRON 2.0: Killer App for the Xbox platform that were never released for the PC version of TRON 2.0. It also includes other fixes and additions for the game. New to the latest version of the mod is 16:9 and 16:10 Widescreen support.
Anon replaces the original Light Cyclist when you see your spawning/driving Light Cycle in Multiplayer.
The reasoning behind this change - aside from bringing in another feature of the Xbox version - is that before, whichever character you selected in Multiplayer would be replaced by the Light Cyclist. It was kind of weird to, say, select a Resource Hog as your MP character and then see him transform into the Cyclist when driving. The new Anon is a more generic model, where you can imagine that your character put on a helmet for riding the LC/SLC. The transition between characters isn't so jarring.
