Command & Conquer: Red Alert 2 Cheats

Desolator Destroyer (Iraq)
To destroy many enemy infantry, get your desolator (or desolators) into the opponent base. (You may want to attack from behind.) As soon as you see enemy infantry in your desolator's line of sight, press d. The desolator will explode, poisoning all the land around it. If any enemy infantry touch the poisoned land, they will die instantly. This is an awesome cheat if you can get your desolator near a barracks. Be warned: the poison disappears after about 30 seconds.
