OEM releasesThis game was basically a showoff title for the then relatively new 3D cards like the Voodoo 2. It also came free with the Creative Labs 3D Blaster Banshee, based around the 3Dfx Voodoo Banshee 2D/3D chipset, and the ASUS Riva TNT graphic card with TV in/out and 16MB SGRAM.
Some OEM versions, e.g. Creative's 3D Blaster Voodoo2 card, were not the full version. They included an early version of the game, and when it was released, owners of the card could send their disc back to creative, and they in return would send back the full game that was released.
