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!
