Killer Bees! (1983)

The Beebots from the insect civilization of BEM are invading the Earth, protected by swarms of Killer Bees, and it's up to a swarm of white bees to stop them. The player control the white bees swarm, trying to kill the Beebots by flying over them and stinging them. The longer the swarm flies over a Beebot, the slower it moves, until it finally stops and dies. When a Beebot dies, a grave marker will be raised in its place, making the movement of the remaining Beebots more difficult. The red Beebots move clockwise, the blue ones move counterclockwise.
