Swarm

Description
Swarm is a 1-player arcade game for the BBC Micro.
The player controls a spaceship that moves across the bottom of the screen and fires up. Enemy ships swoop in circles and fire towards the top of the screen. Enemy eggs appear which, if not destroyed, will hatch into a large enemy vessel that moves laterally across the screen dropping bombs. If the large vessel reaches the bottom of the screen, it creates a hazard that temporarily prevents to player from moving over that location. The player starts with three lives.
