Interphase is a 3D first-person and puzzle video game. The developers were licensed to use concepts from Neuromancer, reflected in the virtual-reality cyberspace concept and theme of a powerful corporation. The game is considered an early first-person shooter, pre-dating Catacomb 3-D and Wolfenstein 3D. However, the game primarily focuses on puzzle-solving using the interaction between a 3D cyberpunk environment and its conceptual relationship with a 2D zoomable blueprint in which a non-player character is indirectly guided through the floors of a high-security building. Later games that have a similar style to the 3D elements in Interphase include Pyrotechnica and Rez. Source: Wikipedia, "Interphase (video game)," available under the CC-BY-SA License.
