Commander Keen in Invasion of the Vorticons: The Earth Explodes

This is the retail version of the original Commander Keen trilogy. You play the role of Billy Blaze, an 8-year old superkid who dons his brother's football helmet and becomes Commander Keen - Defender of the Earth. This trilogy is comprised of the episodes: Marooned on Mars, The Earth Explodes and Keen Must Die! In each game, Commander Keen battles aliens and monsters, wanders through mazes and solves simple puzzles to complete levels. All 3 games are based on the same classic EGA scrolling platform game engine, so the gameplay is consistent through the series. Each of these games is featured here independently.

To the kids at school, you're 8-year-old Billy Blaze. To alien enemies in the galaxy you're superhero Commander Keen and it's up to you to save the Earth from destruction. As you put on your brother's football helmet you'll blast away on your Megarocket to space-worlds far away from home. Your mission: Face off against intergalactic creatures, recover the lost plasma crystals and save humanity -- it's all in a days work. Created by the game masterminds at id SoftwareTM, Commander Keen in the ultimate outer space blast-a-thon!

Trapped in a land where giant vegetables rule the day, you must fight your way through an army of vicious broccoli beasts, savage asparagus warriors and a bushel of other leafy green nasties before battling the fiercest spud of all, King Boobus Tuber. Unless you want a one way trip to the salad bar in the sky, you'll have to finish all your veggies. Before they finish you!

After completing the mission in episode one, Keen learns of the Shikadi's enormous ship, which doubles as the largest weapon ever built. So in episode two, titled "The Armageddon Machine", Keen faces his greatest challenge yet - to save the Galaxy!

A mean bunch of hungry aliens have your babysitter and they're planning to make her their main course. Now it's up to you, as Billy's alter ego Commander Keen, to climb into your homemade Megarocket and save her. Or risk explaining what happened to your parents. The only question is: Can you complete your mission before dinnertime?

Cosmo's parents are taking him to Walt Disney World for his birthday. A comet hits their ship, forcing them to land on an unknown planet and repair the ship.

There are three episodes in the game series in which Cosmo must navigate through 10 alien-themed levels for each episode. In this episode, Cosmo explores the wilds of the Forbidden Planet, utilizing bombs and his suction-cup hands to survive.

An explosive homage to SNES-era platformers mixed with a modern physics-puzzle twist, Explodemon is non-stop action mayhem like you've never seen before. Players use Explodemon's self-destructive nature to combat enemies and fly through the air, all the while solving a huge variety of physics-based puzzles (and, naturally, causing incalculable collateral damage). When the peaceful planet of Nibia is attacked by the malicious Vortex forces, the fate of the star system is thrust into the one pair of hands it shouldn't be: the malfunctioning Guardian robot Explodemon. Featuring 12 huge levels of pulse-pounding platforming, a deep control system, devastatingly up-close-and-personal combat, upgradable special abilities, comic-book style cutscenes and a story that'll make you giggle, cry, or simply sigh with indifference, Explodemon isn't your average game. No way. It's above average, at least. No, wait - so way above average that it's pure awesome. That's more like it. Explodemon! is unrelenting, hard-core brain-tickling action for those who grew up playing platformers, as well as those who'll discover just how awesome they were.
