Blam! Machinehead - Playstation 1 [used]
Blam! Machinehead is a 3D shooter where you shoot enemies and explore the futuristic, barren wastelands and abandoned factories and such as you try to save the world. The player controls Kimberly Stride, who is a scientist. She has to save the world from bad DNA that is slowly "eating" everything away.
As a player, you control an hovercraft which was designed to be a safe vehicle to be in while travelling through this infested world.
The game has nice 3D graphics and a very unique mood to it that separates it from the more common shooters.
