Gentrieve 2 is a "Metroid"-style 3D action game featuring completely random & customizable worlds. The year is 3080. Mass Generators are creating everything, everywhere. However, thieves often steal Mass Generators in hopes of creating robot armies & fortresses. Thieves are terrible programmers, though, and their creations become uncontrollably hostile & fortresses wildly convoluted. It is your job to clear out these fortresses & return the faulty Mass Generators. Be warned, when the Mass Generator is taken offline, the fortress will soon implode!
I've lost more time to this game (and other phr00t games) than anyone has ever spent on any (Theme name here)-Ville game on FaceSpace. I attribute this addiction to the level of environment originality that procedurally generated worlds can provide. The game is as polished as a one-man team developed game can be. It really shows that the author is more of a coder and conceptualist than any sort of professional graphic artist, but it helps to give the game a sort of 'abstract' quality. The sound effects aren't spectacularly unique, but they're form-fitted, and work well with the great soundtrack.
It's games like these that define the 'independently developed' genre.
