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 which are degraded by any weapons fire - yours or theirs - and a quick trigger finger. Occasionally a mothership zips across the top of the screen. When the screen is cleared of invaders, another wave - faster
and more aggressive - appears. When you’re out of “lives,” or when the aliens manage to land on Earth… it’s all over. (Midway [under license from Taito], 1978)
Memories: Three buttons, three colors (if one includes black), all for 25 cents. And thus began the video game boom that made Taito a major manufacturer, with dozens of other companies - Atari, Bally/Midway, Namco, Nintendo, Sega, you name it - riding the large wave launched by Space Invaders. There was indeed an invasion underway…but it didn’t originate from space. It was launched from Japan and Silicon Valley, and for a while…it did take over the world. (Read more about this game…)
The Game: In one of the most seminal variations on the Space Invaders format, Galaxian was among the first clones to introduce attacking formations that would break off from the usual rows and columns of 
invaders. Though Galaxian’s use of this innovation was minimal, it was a drastic change from the usual slowly-advancing target gallery. (Bally/Midway [under license from Namco], 1979)
Memories: Galaxian may not be as well remembered as the much more strategically challenging Galaga, but it ultimately added a vital new twist to the Space Invaders-inspired genre, a format which was badly in danger of becoming stale. Galaxian was also the first arcade video game to use a color display instead of a monochrome monitor with translucent colored overlays. (Read more about this game…)
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)
Memories: In the wake of virtual shooting gallery games like Space Invaders, Carnival arrived on the scene to make the shooting gallery metaphor more literal. Well, more or less - killer ammo-grabbing ducks aren’t exactly standard issue at the state fair. (But seeing how much finesse they add to Carnival, they should be!) (Read more about this game…)

The Game: Manning a fairly agile cannon located on a platform at a castle, your task is simple: protect the King! However, there’s a flotilla of even more agile balloons above you who are there to kidnap his royal highness. As the King is hoisted away by his assailants, he yells “Help!” If you shoot down the offending balloon, the King
shouts “Thank you!” as he floats back to the safety of the castle via an umbrella. The balloons can ram your cannon kamikaze-style and flatten it for a few seconds, but curiously, you have an unlimited supply of cannons. However, if the balloon marauders get three Kings off the screen, your game ends. (Namco, 1980)
Memories: One of the most bizarre and obscure entries in the resumè of Namco (also responsible for classics like Galaga, Xevious, Dig Dug and a little thing we call Pac-Man), King & Balloon comes across as nothing so much as a bizarre attempt to repurpose Galaxian into a cutesy game. The one-shot-on-screen-at-a-time, the attack patterns of the balloons and some of the sound effects hammer the similarities home. (Read more about this game…)

The Game: As commander of the three-stage fighter rocket Moon Cresta, your job is to ward off endless varieties of evasively weaving space attackers. Every time you knock out two consecutive screens of assailants, you’ll have an opportunity to dock your ship to another one of Moon Cresta’s three stages, until all three
portions of the ship are combined to create one bad-ass weapons platform. But you can also lose stages very quickly, ending your game - a bigger ship makes a bigger and easier target. (Sega/Gremlin [under license from Nichibutsu], 1980)
Memories: Moon Cresta had a very cool idea which was ripped off by a handful of its contemporaries - instead of giving the player a set number of “lives,” players had three rocket stages. Losing even one stage could seriously hamper your life expectancy in the game in later levels, and you could lose a stage to anything from enemy fire to not lining your stages up correctly during docking. This actually made Moon Cresta a very challenging game - but also a very fun one. (Read more about this game…)

The Game: Apparently, the exterminating business is getting more dangerous. In the course of trying to wipe out some vermin, you find yourself on the defensive - any of them can kill you simply by touching you. Fleas drop from the top of the screen, leaving bothersome mushrooms in their way. Scorpions periodically
poison the mushrooms, making them impossible to destroy. And a pesky spider is always dancing around the screen. (Atari, 1980)
Memories: I was never that hot on Centipede, but this is mainly due to the fact that its trakball controller pretty much ensured that I sucked at this game. But many people just loved it. With the benefit of hindsight, and slightly better hand-eye coordination, I can now see why. (Read more about this game…)
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. (Read more about this game…)

The Game: Commanding a small fleet of sleek fighter ships, you’re up against an alien invasion, arriving in wave after unfriendly wave. Alien fighters resemble butterflies and bees, but the real prize is the handful of motherships which arrives with each wave. Capable of taking two hits - the first weakens them and turns them dark blue, the second destroys them - the motherships also come equipped with a tractor beam with which to snare your fighters. But if one of your fighters is captured, and you can destroy the
mothership which is towing it, your wayward fighter will be returned, doubling your firepower. (Bally/Midway [under license from Namco], 1981)
Memories: Where its predecessor, Galaxian, brought “attack formations” to standard Space Invaders-style shooters, Galaga introduced real strategy, and influenced nearly every shooter that came after it. (Read more about this game…)
The Game: The evil Gorfian Empire is attacking, and for only a quarter, you can enlist and defend Earth against the vicious (yet strangely cute) little critter with a robotic voice. In the first stage, Astro Battle, you have a defesive shield which is weakened with each shot the aliens fire at you - and every shot you fire back at them. (Truth be told, it’s a very thinly disguised take on the Space Invaders formula.) Then, in the Laser Attack level, the aliens break out heavier, nastier artillery that you have to dodge…if you can. Stage 3 sees a guest star from an earlier Midway game in the Galaxians stage, which is a sort of scaled-down version of the Galaxian game itself. Stage 4 is the hardest, with the Gorfian menace repeatedly spiraling out of a Space Warp, defying you to get so much as a single good shot fired off at it. Finally, if you survive the fourth stage, the Flagship level awaits. The flagship can fire any number of projectiles in your direction through your shield, and you have to not only dodge incoming fire, but try to get your own shot to hit just the right place on the flagship to destroy it. (Bally/Midway, 1981)
Memories: Gorf was a minor hit in its time, though this latest attempt to turn the Galaxian format into a franchise fell through the cracks. It didn’t help that the first stage seen in the attract mode was a Space Invaders clone. (Read more about this game…)

The Game: 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 which are degraded by any weapons fire - yours or theirs - and a quick trigger finger. Occasionally a mothership zips across the top of the screen. When the screen is cleared of invaders, another wave - faster and more aggressive - appears. When the aliens manage to land on Earth…it’s all over. (Mattel, 1981)
Memories: Sound familiar? It should. This early entry in Mattel’s library of Intellivision games is, rather obviously, a not-very-thinly-disguised version of Space Invaders, the game whose home version had made the Atari 2600 a household name in the home video game biz. (Read more about this game…)
The Game: Piloting a lone spaceship zipping over a planet’s surface in a low, fast orbit, your mission is to kick some evasive alien butt. Drawing a
bead on the aliens is much harder than it looks, and they arrive in waves of four. Naturally, it seems like it’s much easier for them to target you… (Games By Apollo, 1981)
Memories: Quite an improvement over Richardson, Texas-based Games By Apollo’s first game, the disastrously bad Skeet Shoot, Spacechase isn’t going to blow the doors down in the game originality department, but it wasn’t bad for the VCS at all. The scrolling planetscape beneath the player’s ship may look like an artist’s vague impression of some Arizona landscape, but with games like Defender struggling to get the side-scrolling thing right, it was quite an accomplishment. (Read more about this game…)
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 quartet of shields which are degraded by any weapons fire - yours or theirs - and a quick trigger finger. Occasionally a mothership zips across the top of the screen. When the screen is cleared of invaders, another wave - faster and more aggressive - appears. When you’re out of “lives,” or when the aliens manage to land on Earth…it’s all over. (Texas Instruments, 1981)
Memories: A straightforward, no-frills take on Space Invaders, TI Invaders trumped just about every other home computer version in terms of faithfulness to the source material. (Read more about this game…)
The Game: As commander of the three-stage fighter rocket Eagle, your job is to ward off endless varieties of evasively weaving space attackers. Every time you knock out two consecutive screens of assailants, you’ll have an opportunity to dock your ship to another one of Eagle’s three stages, until all three portions of the ship are combined to create one bad-ass weapons platform. But you can also lose stages very quickly,
ending your game - a bigger ship makes a bigger and easier target. (Centuri [under license from Nichibutsu], 1982)
Memories: Don’t ask me what happened here. I distinctly remember playing both Eagle and Moon Cresta in the arcades and thinking how similar they were. Much later, with the benefit of emulation, I could play both back-to-back and realized what I’d always suspected: they’re the same game! (Read more about this game…)

The Game: Once more unto the breach, your garden of mushrooms is now under attack by a millipede, and the big bug’s even nastier insect entourage has come along too. The spiders, scorpions and fleas are now joined by mosquitoes and inchworms, among others. The only advantage you have? Occasional containers of DDT (can you tell this was the 80’s?) will allow you to wipe out all targets within a given radius…but use them wisely! (Atari, 1982)
Memories: Another rare Atari sequel - from a company that tended to at least try to stay away from repetition - Millipede of course picks up where Centipede left off - in the same garden, with lots of bugs. A major ad campaign kicked this one off, with Atari using the then-world-champion of Centipede as a spokesperson to verify that this game was, indeed, fun and challenging. (Read more about this game…)
The Game: Your planet is under siege by an unending hail of asteroids, bombs, and space debris. Your simple mission? Blast all of this stuff, or dodge it. But you’re toast if a bomb hits the ground. (M Network [Mattel], 1982)
Memories: Not one of Mattel’s finest titles for the 2600, Astroblast is a loose adaptation of Astrosmash, a game originally released for Mattel’s Intellivision console. The graphics are clunky even compared to such bottom-of-the-barrel entries like Atari’s Pac-Man and Combat. (Read more about this game…)
The Game: The game begins as the skull-like face of Spyruss the Deathless (the Timelord of Chaos, no less!) taunts you (well, only if you had the Voice), and then a bunch of pesky spaceships pops out of a vortex to shoot at
you. They shoot at you rather a lot. Fortunately, you can shoot back with reckless abandon, but their ammunition - as you ascend into the higher levels of the game - can track you and even, if you don’t destroy their shots in mid-air, crawl along the ground briefly while you head for the opposite side of the screen, neatly trapped for their next volley. (North American Philips, 1982)
Memories: One of the last few games to be made for the Odyssey 2, this gem of addictive shooting-gallery fun is obviously heavily derived from the all-time arcade classic Galaga. (Read more about this game…)
The Game: Centipedes, spiders and fleas invade your garden of ’shrooms. Spiders follow an evasive course and can collide with you at any moment. Fleas poison the mushrooms, making them impervious to your fire (and thus giving the
centipede impenetrable cover). And the centipede itself can split into many segments, and if it reaches the bottom of the screen, will turn around and start to move upward again, possibly catching you from behind. Every time you manage to completely “debug” the screen, you move up to a harder level. (Atari, 1982)
Memories: Centipede was a huge arcade hit, so it’s no wonder Atari wasted no time in creating the home translation. Though the Atari 2600 version of the game couldn’t compete with its arcade ancestor’s colorful graphics, the home version did get the point across. (Read more about this game…)
The Game: Aliens are after your kids! Fortunately, you’re armed with a resource that not everyone has: your own flying saucer. In the opening screen, you have to return to the saucer to resume command, and then you signal your kids to come up, one by one, as you try to pick off alien pursuers who are hot on their trail. If you’re
not careful, you can actually zap the kids instead. If an alien manages to reach your saucer, someone else will have to give your kids a ride home from the star academy… (Telesys, 1982)
Memories: It may not have been the biggest, most obvious name in software for the 2600, but I have to give Telesys top marks for coming up with cool ideas for their games. Cosmic Creeps is a great example of what Telesys was best at, and it’s a lot of fun too. (Read more about this game…)
The Game: Demons coalesce into existence in mid-air above your cannon. Send them back where they came from by force - but watch out, as demons in later levels split into two parts upon being hit, which must then be destroyed
individually. After fending off several waves of attackers, you blast off to deep space to confront their mothership. (Imagic, 1982)
Memories: No bones about it, the Intellivision version of Demon Attack is the definitive version of this game. It also drew a lawsuit from Atari, who had just licensed the arcade game Phoenix from Centuri (an American operation which had, in turn, licensed it from Taito in Japan). In a lot of ways, Phoenix and the Intellivision version of Demon Attack were very much alike - swooping alien attackers who split into two equally lethal halves when hit, and a Comet Empire-like alien mothership with only a single vulnerability (and an endless stream of defensive fighters to cover that weakness). (Read more about this game…)
The Game: In one of the most seminal variations on the Space Invaders format, Galaxian was among the first clones to introduce attacking formations that would break off from the usual rows and columns of
invaders. Though Galaxian’s use of this innovation was minimal, it was a drastic change from the usual slowly-advancing target gallery. (Atari, 1982)
Memories: Like the 5200 version of Pac-Man, Galaxian is a good demonstration of the next-generation Atari console soundly trouncing its older brother. Galaxian is no slouch on the Atari 2600, but while the game play is relatively intact, the look and feel of the arcade game didn’t survive that particular translation. Those elements are handled much more faithfully in this version of the game, though. (Read more about this game…)
The Game: What happens when the Dreaded Dratapillar Of Venus makes a guest appearance? It means that a spelling bee is imminent! A friendly voice warns you to look out for a “monster attack,” and after dispatching all of the segments of the worm-like invader, you’re asked to correctly spell three words using the Odyssey2 keyboard. Once you’ve correctly spelled those three words, another monster attack occurs, with the Dratapillar moving faster in each successive level; the game continues until it descends far enough down the screen to reach your cannon. (North American Philips, 1982)
Memories: Programmed by Sam Overton, SID The Spellbinder! was one of the first two - and, as it so happened, only two - educational launch titles made available specifically for the then-new Voice Of Odyssey speech synthesizer. (Read more about this game…)
The Game: You’re the pilot of a ground-based mobile weapons platform, and there are buttloads of alien meanies headed right for you.

When the screen is cleared of invaders, another wave - faster and more aggressive - appears. When you’re out of “lives,” or when the aliens manage to land on Earth… it’s all over. (Atari, 1982)
Memories: Adapted from the Atari 400/800 home computer version of the coin-op hit, Space Invaders for the 5200 is certainly colorful, though one could argue that it’s ultimately not as faithful to the original as the graphically simpler version that appears on the Atari VCS. (Read more about this game…)
The Game: As Stanley the gardener, you’re trying to repel a swarm of pests unleashed by that meanest of pixellated gorillas, while also using your pesticide to propel him off the screen. Protect your flowers and yourself, and wear plenty of Off. (Nintendo, 1983)
Memories: The third entry in the still-ongoing series of games spawned by the original Donkey Kong, Donkey Kong 3 wasn’t as successful as the previous sequel, Donkey Kong Junior. One possible reason for this could be Nintendo’s brief abandonment of the climbing/jumping game elements in favor of a shooting game whose roots could easily be traced back to Space Invaders. (Read more about this game…)
The Game: The aliens are taking their complaints to the home office! As the pilot of an agile space fighter, you have to blast your way through the alien forces from Pluto all the way back to Earth. Occasionally you can boost your ship’s firepower, but that’s the only help you’re going to get. The rest is up to your speed, your 
strategy, and your ability to nail the attackers in mid-dive. (Centuri [under license from Konami], 1983)
Memories: Konami’s cult classic basically put a vaguely Tempest-esque 3-D spin on the strategy of Galaga, borrowed some music from a certain Mr. Bach and blasted it out as a stereo techno-symphony, and got a lot of people to blow their hard-earned money. It was also a lot of fun. (Read more about this game…)
