Hovertank 3D
Hovertank 3D is a computer game from id Software published by Softdisk that sometimes if claimed to be the first first-person shooter or even the first 3D game for IBM PC. The game used the same combination of scaled sprites and drawn walls that would later show up in Catacomb 3D and Wolfenstein 3D, but the walls in Hovertank 3D was in solid colour, without any textures.
