Comrade Keen is a Communism-themed mod made by StupidBunny. It was abandoned, but released in a beta state featuring 8 fully playable levels with completely new graphics and enemies, but no ending.
Billy Blazovski, eight year-old genius, working diligently in his governmentally assigned clubhouse has created an interstellar starship from old soup cans, rubber cement and plastic tubing. While his folks are out farming and the babysitter has fallen asleep, Billy travels into his backyard workshop, dons his American (OMG, Westernization!) football helmet, and transforms into...
COMRADE KEEN--defender of communism!
In his ship, the Borscht-with-Boby Megarocket, Keen dispenses socialist justice with an iron hand!
- DEFEAT THE SPACE MENSHEVIKS!!!
One fine day in the good ol' U of SSR in 1965, Comrade Keen finds the Earth being surrounded by a race of evil jerboa-like space aliens, the Menshevoids. When their first soldiers land, they head straight toward Moscow to bring down the Communist Party. The Soviet Red Army manages to keep them away for now, but they'll strike again...with reinforcements!
- WHERE THE MENSHEVOIDS LIVE
Comrade Keen eventually finds out that they are attacking from Vladimir V, a distant planet in another galaxy. He takes his ship there, intent on looking for ways to stop them.
As it turns out, they work their system exactly the same way that the Soviets do--they even use the same flag. Keen figures that, if he could only find the data disks that hold all of their government information, he could bring it before the Party in Moscow. Then they could sue the Menshevoids big-time!
- LIFE ON VLADIMIR V
Besides the Menshevoids, Vladimir V is also home to the blue, ghostly, yet very friendly Zleebs, the tough, mean Praxes, and the poisonously nauseated reptiles, the Shnogeks. Before the Menshevoids introduced Communism as their government, the Zleebs had been living happily under a nice stable Capitalist system. But then, the Menshevoid Revolution changed their ways, and they were harshly ruled by these unfriendly rodents.
The Standard Galactic Alphabet is not used on Vladimir V, but the Cyrillic Terran Alphabet and Zleebish are both used. There is rumored to be a translation of the CTA into the SGA...where it is up to you to figure out.
So now, you, as Comrade Keen, must go out and find those Data Cards, and let the law do the rest! And if you don't, then the world will be entirely under the Menshevoids Stalinist paws!
Spoiler Warning! This shows the whole levels.
