Warheads SE is a remake of WarHeads. The turn-based gameplay is similar to
games like Tank, Scorched Earth, and more recently Worms, except it now takes
place in space and gravity is not only pulling the space ship’s missiles down,
but towards any nearby planet. There is a large variety of weapons to take out
enemy ships. The shareware version is fully playable, but only the registered
version allows custom weapons. The game supports both single-player and
multiplayer games.
