Space Attack is a 1-player arcade game for the VIC-20.
The player controls a small vessel at the bottom of the screen that moves horizontally and fires vertically. Numerous alien vessels approach from the top. These vessels move side to side, and fire angled and straight shots. The player gains 10, 20, 30, or 40 points depending on the ship destroyed. Progressively faster aliens appear as the game progresses. There are 3 skill levels, and the player has 3 vessels each game.
Space Attack is a shoot 'em up that mixes elements from a number of popular arcade games of its time. The player's task is to defend a city which, like in Missile Command, occupies the bottom part of the screen. The city is being attacked by aliens unleashed by a feared warlord who aims to fully destroy it. The aliens attack from above and move around in patterns similar to fixed screen shoot 'em ups like Galaxian. They drop bombs on the buildings on the surface and the player has to shoot them down before they do so. Controlling the spaceship is similar to Asteroids, with a combination of thrust and rotation allowing it to move all over the screen and shoot in any direction. In addition to the regular fire, a super weapon can be used but it's limited to three uses. Another thing to watch out for is the fuel level of the ship. It's necessary to land and refill it before it runs out.
An adaptation of Snake where your multi-segmented character represents a garden hose: move it about in four directions across the playfield, collect targets to proceed, and make sure to avoid your own tail and other barriers.
All targets ("faucets") shown on screen must be picked up before the timer runs out. In earlier levels you only get one at a time, but this later increases to two and three; if you take too long, a new set appears and your hose grows longer as punishment. Beat the clock three times to proceed to the next "yard", with an extra life ("spare hose") for your trouble. Later levels also set the "pressure valve" higher, which increases the timer's speed.
Two different level sets are included: in the "amateur" levels, movement controls behave as you'd expect, and you turn at right angles; the "professional" levels feature a pseudo-isometric scheme, where the vertical axis becomes diagonal, to make things trickier.
Outhouse is a single screen shooter played from a side view perspective where the player has to defend the titular outhouse from toilet paper thieves. The outhouse is located in the middle of the screen and the thieves come wandering in from either side. The player controls a flying craft and has to shoot the thieves before they manage to reach the outhouse and get away with the paper. Once the thieves reach the outhouse they move back to where they came from leaving a trail of paper behind and if they leave the screen the paper is lost. If shot before they leave, the paper is returned to the outhouse. There are also squatters that enter the outhouse and use up some paper directly. Other obstacles and enemies include fireballs, zappers (that that move down the sides of the screen and shoot at the player) and other flying objects that needs to be avoided. In addition to the regular laser the player also has a limited amount of smart bombs that kill everything on screen. The game ends when there is no paper left, the
