Three entries, ProtoShooter, Frobot, and Egg Worm Generator were submitted. The last is the most interesting of the group, though, is not even a shooter anymore (the game became a fishtank with the shooting aspect dropped). ProtoShooter might have been interesting with its time-based mechanic, but it suffers from under powered weapons. Frobot has lots of style, but it is pretty standard take on Robotron.
