From Melbourne House:
KKnD Extreme takes carnage to a new level with this sequel to the original KKnD (Krush Kill 'N' Destroy) game. As in the first game, in 2079 a massive nuclear war turned Earth into a violent killing field, and different civilizations and cultures now fight over the remnants. The object of this game is to destroy your enemy, as one of the survivors, or as one of the evolved races. Accomplish your goal by building units and attacking the enemy, as well as defending against ceaseless attack. Drill for oil, construct new buildings, and see who wins. This demo version lets you play four levels.
