This patch will allow you to run StarSiege (not TRIBES) under Windows 2000.
This patch is for those of you with an OEM version of Starsiege, meaning you got the game bundled with hardware of some sort. Do note that this is not Starsiege: TRIBES... just plain old Starsiege.
Upgrades version 1.003 of Starsiege to version 1.004. See "More Info" for a list of new features.
