Impact

Impact is a 2 - 4 player arcade game for the 8-bit Atari computer.

Each play controls a skimmer, which can move in all directions, and has inertia. Each skimmer is armed with a bumper, which will temporarily enact a forcefield around their vessel. If the player hits an unshielded vessel, they'll destroy it. After the shield expires, that vessel is temporarily defenseless until the shield can recharge. If 2 unshielded vessels collide, both are destroyed. Each player starts with the same number of vessels, and the last player standing is the victor. Players can set a timed game, and can give different players a handicap, allowing their shields to last longer. There are 17 different game boards to choose from.
