New to Version 1.1a of the mod is compatibility with the Steam version of TRON 2.0, easier installation, v1.1 bug fixes, and restored Multiplayer support in-game on both the CD/DVD and Steam versions. 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, such as 16:9 and 16:10 Widescreen support.
The Sequencer is just one of the powerups that has been redesigned to look better in v1.2, compared to the original retail game and previous versions of the mod.
