Invaders From Hyperspace!
The Game: One of the earlier Odyssey2 space-related titles pits two players against a pair of pesky alien saucers. (It is theoretically possible to play this game solo, but it’s much more fun with two players, as many Odyssey games were.) The game play is almost simple: two planets, each with a system of four moons, orbit their way around the screen. The object of the game is to occupy the most territory by shooting the planets or moons until they change to the same color as your ship. The alien saucers, however, are also doing this, making life extremely difficult. They can also set their sights on you, destroying your ship. You can return to the fray if any planet or moon on the screen is the same color as your ship, but if the aliens blast that body before you’ve taken off again, you’re trapped until the next window of opportunity arises. (Magnavox, 1979)
Memories: The genius of this graphically simple game is that the two players can team up…or they can wage a three-way war against one another and the aliens! [read more]
The Game: Get out there and draw! Your cowboy faces off against another player, or the computer, in a fight to see who can draw their gun the fastest – and who can run away the fastest! (Magnavox, 1979)
The Game: As a lone space pilot flying down a seemingly endless trench, your job is simple – blast or bomb all of the vaguely-bow-tie-shaped space fighters that you see. If your fighter is on the lower half of the screen, you’re blasting straight ahead/upward; if you move your fighter near the top of the screen, you can bomb any fighters below you. The game ends when you run out of ships; fortunately you never seem to run out of ammo. (Bally, 1979)
The Game: Zylon warships are on the rampage, blasting allied basestars out of the sky and wreaking havoc throughout the galaxy. Your orders are to track down the fast-moving raiders and destroy them before they can do any more damage. You have limited shields and weapons at your disposal, and a battle computer which is vital to your mission (though critical damage to your space fighter can leave you without that rather important piece of equipment). The game is simple: destroy until you are destroyed, and defend friendly installations as long as you can. (Atari, 1979)
The Game: One or two players are at the controls of speedy ground assault vehicles which can zip around an enclosed maze of open areas and buildings with almost mouse-like speed. Heavy tanks and armed helicopters routinely appear in this maze, attempting to shoot any player vehicles they spot; the player(s) can, in turn, fire back at both of these vehicles. Caution: a damaged tank may still be able to draw a bead, so it’s best to keep firing until the tanks are completely destroyed. (Cinematronics, 1980)
The Game: As the pilot of a lone space cruiser, you must try to clear the spaceways of a swarm of free-floating (and yet somehow deluxe) asteroids, but the job isn’t easy – Newton’s laws of motion must be obeyed, even by asteroids. When you blow a big rock into little chunks, those chunks go 
The Game: You’re alone in a maze filled with armed, hostile robots who only have one mission – to kill you. If you even so much as touch the walls, you’ll wind up dead. You’re a little bit faster than the robots, and you have human instinct on your side…but even that won’t help you when Evil Otto, a deceptively friendly and completely indestructible smiley face, appears to destroy you if you linger too long in any one part of the maze. The object of the game? Try to stay alive however long you can. (Stern, 1980)
The Game: Step right up, put your quarter on the table (well, okay, technically in the slot), and take your best shot. There are plenty of targets to hit, but no big plush bears to win. If you don’t take out the ducks before they reach the bottom row, they don’t cycle back to the top like the other targets – they start flying and can take serious amounts of ammo off your hands and end the game early! (1980, Sega)
