DF Retro: Gunbuster vs Wolfenstein 3D - How 1992 Revolutionised The FPS

Haven't heard of Gunbuster, or Operation Gunbuster? We're not surprised. It's an arcade shooter from 1992 released mere months after Wolfenstein 3D re-architected the first-person shooter on PC. The thing is... there's a lot of commonality here in terms of presentation, movement and control with the key difference coming down to technology. Gunbuster's entire presentation is based on sprites, a dead-end technology for the FPS revolution to come but in 1992? It was the Wild West and anything was possible.
