Alien Invaders – Plus!
The Game: It’s quite simple, really. You’re the pilot of a ground-based mobile weapons platform, and there are buttloads of alien meanies headed right for you. Your only defense is a trio of shields and a quick trigger finger. If your cannon is destroyed, its pilot must run for cover; each of the three shields contains an extra cannon. When all three shields are gone, the alien commander – a kind of spaceborne crab – will descend to nearly ground level and hunt the helpless pilot down. Ten rounds of this decide the outcome of the war. (Magnavox, 1980)
Memories: Alien Invaders – Plus! was the first Odyssey 2 game I got hooked on, and my mother just thought it was riotously funny, especially the bit where the giant space squid floats down from the top of the screen to chase your unprotected gunner around when all of your defenses have been depleted.

The Game: You start the game by creating a character, Basic D&D style, who enters the world defenseless and just this side of naked. It’s your job to arm and armor your alter-ego, buy plenty of rations, and then set out to explore the world of Britannia, and the treacherous dungeons that lie beneath it. A visit to the castle of Lord British will give you a chance to level up for deeds accomplished, and receive an assignment from him for your next adventure. (California Pacific Computer, 1980)
The Game: Another day, another alien invasion. But this time it won’t be so easy to fight the aliens off: your ship has a limited supply of power, and your guns can overheat if you force them to spend too much time blazing away. You have to be judicious with your firepower, dodge incoming fire, and hold out long enough to dock with your own mothership and refuel between waves. (Gremlin/Sega, 1981)
The Game: The end of the world is near: asteroids and meteors are careening toward the surface of your planet at breathtaking speeds. Manning a speedy mobile laser cannon, your job is to take out or dodge the falling fragments from 
The Game: I’ll try to explain this as best I can. You’re a paintroller (recent escapee from Make Trax?) beseiged by pigs. Or a gorilla pursued by natives. Or something like that. It depends on which level you’re playing. You must try to enclose as many of the spaces in the game area as possible, in a zig-zagging pattern. This, the attract mode wisely advises us, is “Amidar movement.” You have one way to avoid an imminent head-on collision – you can hit the jump button, which doesn’t make you jump, but forces everything else on the board to jump. Enclosing all of the available spaces advances you to the next level, with different animal enemies. (Stern [under license from Konami], 1982)
The Game: Help Mr. F. Lea get to the top in this dog-eat-dog world. Cross a treacherous yard full of lawn-mowers (and helpfully slow-moving dogs), swing from tail to tail until you’ve jumped on every dog on the screen, scale the big dog’s back and jump over his spots, and climb to the top of Dog Hollow while avoiding the dog toys and bones being thrown at you from the top of the screen. You’d better be itching to win. (Pacific Novelty, 1982) 
The Game: Your quest begins as you set out from the safety of home to look for adventure in mountainous caverns. When you wander into the dungeons and caverns, your view zooms in to the maze your adventurer is exploring, complete with treasures to collect and deadly dangers to duel. (Mattel Electronics, 1982)
The Game: As video warrior Tron, you scale the heights of the MCP’s domain, avoiding Tanks, Recognizers and Grid Bugs, and trying to collect Bits. You can occasionally hitch a brief ride on a perpetually airborne Solar Sailer on one level, allowing you to fly over your opponents’ heads for a few seconds. (M Network [Mattel], 1982)
