Simple Bots is a game of giant robot, tank, and powered armor (mecha) combat. The game can be played standalone, as a pure combat game, or it can be used to supplement the Frontier Horizons role-playing game by providing mecha/tank combat rules for characters. The rules are hex-based and combat segment based. The rules present construction methods, sample bots, and numerous scenarios with maps. The rules probably will feel more familiar to war gamers than role gamers.
