Commodore VIC-20 - Released - 1983
Your job is to guard the supplies at the lunar base. Bandits of various sorts arrive in waves and descend, trying to get the goods. Armed with a mobile laser gun and some shielding, you score points by blasting the bandits. Bandits has 28 levels of play. You begin with 5 ships and acquire a bonus ship for every 5,000 points. The game is similar to Space Invaders. It also bares some resemblance to the arcade game Rip Off.
Apple II - Released - 1983
Drol is a platform game where you play a cute robot that can fly and shoot. Your goal is to rescue children that are wandering around each level. The levels consist of rows of platforms, with gaps which can be jumped through to go up or down a vertical level. The creatures to avoid and shoot vary from strange hopping, beer-belly aliens, to demons, snakes, and axes flying through the air (we never do find out who's throwing those axes!). Like Defender, Drol incorporates a "radar" at the top of the screen, so you can find the children and dodge incoming baddies.
