Tank Wars. Scorched Earth. Bang Bang. Dome Wars. Worms descends from classic party games firmly rooted in multiplayer versus play. The slow-paced, enjoyable game mechanic is turn-based, 2D ballistic artillery which you can manually aim at each other's worms. In a standard single or multiplayer game, each side starts with four worms, and wins by inflicting sufficient damage to each opposing worm without losing all of its own worms.
