Massive Assault is a 3D hex-based wargame. You won't see hexes all over the map, however, as little circles indicating hexes appear only when you need them. It is a simple turn-based game, with minimal rules. You control an army of sci-fi vehicles, and fight for control of various countries across small islands or massive archipelagos. The game is rendered in full 3D, complete with water effects. Some critics describe the game as being more of a puzzle than a strategy game, as a few wrong moves will often lead to defeat.
