Alien Addition is an educational game that mixes maths problems with the gameplay of a shoot 'em up. The player controls a cannon left and right along the bottom of the screen and has to shoot down the aliens space ships that appear above him. There are five ships in a row and they slowly begin descending down the screen. Each ship has a maths problem written on it and to shoot it down the player has to enter the correct answer for the ship above him. The player is destroyed if any ship reaches the bottom. The game otherwise runs for a fixed time which can be customized by the player. Other customization options include skill level (1 to 9) and problem range (3, 6 or 9).
With the beginning of a new game, a map screen is shown with the player's position, as they control a ship set in a series of interconnected caverns. They must first plan out the best route in order to get to the central area in each Mission.
After several seconds, the map screen changes to a cavern that the player is currently in, which each cavern has a core in the center that is constantly growing, as well as having several Planet Protector enemies. It is usually in the player's best interest to clear out each area of Planet Protectors by shooting them, then carefully inching their way to the protective barrier by an exit in order to drill through it. Once the barrier has been disabled by the drill, the player can then fly into the next cavern and thereby gets a step closer to the central area.
The view changes from a cavern to the map screen with each cavern that they pass, showing the player's(') progress. Once the central central area is reached, the player(s) must drop a bomb at the center core, which they
Satan's Hollow is a shoot 'em up arcade game released by Bally Midway in 1982, subsequently converted to the Atari 8-bit family, and in 1984 to Commodore 64.
Piloting a pie-shaped spacecraft, you must move from sector to sector collecting treasure while avoiding enemies and corner-mounted lasers. The more treasure you have with you the higher your bonus when you reach the goal. A "thief" roams the sectors collecting treasure at the same time, but shooting the thief causes him to drop all his treasure.
As in the arcade game of the same name, Blueprint gives you, as J.J., three chances to save the damsel in distress from a menacing creature chasing her across the top of the screen. Navigate J.J. through a maze of houses, which contain either a piece of the Rube-Goldberg-esque monster-fighting contraption whose blueprint lies at the bottom of the screen, or a bomb which must be disposed of in short order. Pressing the button will make J.J. run faster, but like so many who spend a lot of time sitting at the Atari 2600, he has a limited amount of "Fast run time" (as indicated by a handy bar graph). Smaller but still pesky monsters also pop out of the bomb disposal pit and try to prematurely start the machine (which shakes it to bits). Once that occurs, those monsters must be lured back to their pit, and the machine must be reassembled.
Build the machine in time, and you can blast the creature who's chasing your girlfriend. The Atari 2600 edition simplifies the graphics drastically (though the most elaborate part of
Pepper II is a maze game with zip! The object of Pepper II is simple enough, all you do is zip closed sections of the maze and they will become filled with color. Zip in all the sections of the maze and it's complete. However, if you backtrack you might unzip your path, so be careful! Each stage has four mazes you must complete to move on, but you can move from maze to maze by using the exits located at the top, bottom, and sides of the screen. And don't forget about the bad guys trying to take you out all the while. If one touches you you're toast! You can fight back by zipping sections of the maze closed that contain power-ups that will make you invincible for a short time or clear the screen of all the baddies. The game keeps getting harder as you progress to higher stages.

Horizontal space shooter. You are a fighter pilot on several hazardous missions. In each level you have to fulfill one mission like bomb the radar, destroy the tank etc. The scenery as buildings and warehouses and airborne objects as jets and rockets can all destroy your jet. Your fighter jet is armed with a limited supply of bullets for an on-board machine gun and with bombs, also with limited supply. Bombs can only be dropped from very low altitude. Furthermore, your jet has a limited amount of fuel which can be refueled by picking up a parachute dropped out of another plane.
Clean Sweep is an arcade puzzle game. Move a vacuum through a maze in order to suck up dollar bills that are strewn throughout the screen. After several bills are vacuumed up, the vacuum will increase in size. After several size increases, the vacuum will become full and will not be able to vacuum up any more bills, so the money must be deposited in the vault in the center of the screen before the vacuum can start gathering up money again. The difficulty level increases by having the vacuum fill up quicker, causing the player to make multiple trips to the vault during a level.
Slither is similar in nature to the hit arcade game Centipede by Atari. You control your snake as it slither's around the screen. Where this game differs greatly from Centipede is that you can shoot in 4 different directions at the same time to take out the baddies trying to hunt you down. The bad snakes hunting you down will appear from various angles on the screen, often several at a time. The game was bundled with Coleco's Roller Controller and can't be played without it.
