Invincible Legion keeps the style of the game.I add only a few new units but strengthened the ones that were considered "useless". The mod has the most fierce AI ever seen.Try to survive!If you are more interested,there is a game mode for super advanced AI killers. Enhanced with NPExt.
unpack everything in the release to your Yuri's Revenge folder,replace every file to install the mod.Backup gamemd.exe
