Megatack

Megatack is a space-themed fixed screen shooter with a lot of similarities to Centuri's later game Challenger . You control an armed space-pod that can move left and right along the bottom of the screen. There are two stages that alternate. In the first, monsters appear from the top of the screen while dropping bombs. You have a three-way shot, and need to take out the wave of 25 aliens before they devour you. The second stage contains space rings, that wobble about the screen slowly growing in size. Some of the rings will break into smaller rings if you shoot them. In this stage you only have a single-way shot but have a higher rate of fire. You have to destroy all of the rings before they get too large and engulf your space pod.
