X-COM: Gladiators is a remake of tactical part of X-COM: UFO Defense (UFO: Enemy Unknown) game. It uses all the graphics and sounds from that game (you have to unpack ufo2000 into the folder with UFO1 or at least with content of ufo2000dat.zip) and adds only one new feature - multiplay and one enhancement - 640x400 resolution .
The game requires that you have a copy of UFO to play so I think it's Ok to post a link to it
actually i can play it without the ufo game, i just downloaded the .dat zip and the .exe zip and put it in one file. but of coarse it didn't work cause it wanted a .dll file so i dloaded that to and now it seems to work i just have noone to play with at the momment. if anyone wants i can put the whole thing on my website. are you getting a .dll problem blue? or does it just crash your system.
