A lot of fun.
Warheads is a great game, and a very welcome alternative to other Scorched Earth style games. The AI is a worthy opponent, the weapons are varied and interesting, and the humor and style of the game is very well presented. The random map creator is a very welcome addition, as it gives the game near infinite longevity. Having short rounds with a couple opponents, or long drawn out matches with many opponents makes the game fun for both a few minutes, or for several hours. Highly recommended, especially if you like Pocket Tanks or Scorched Earth.
