Frenetic

Release date: 1991
Platforms: Amiga, Atari ST

The Earth has been under siege by evil aliens from the planet MOZONE for centuries. The planet can not be saved - it's time to find a new home for humanity. A heavily armed ship is sent ahead to scout for such a place - naturally, lots of MOZONE ships stand in the way.
Frenetic is a vertically scrolling shoot'em'up. The action moves through eight levels, set both in space and on the ground (with such environments as a jungle planet and a water world).
