Quake

id Software's Quake arrived in 1996 as the first fully 3D first-person shooter, replacing Doom's pseudo-3D engine with true polygon environments. It pioneered online multiplayer deathmatch over the internet — not just local networks — and featured a landmark industrial soundtrack by Nine Inch Nails' Trent Reznor. Quake's engine technology and multiplayer infrastructure shaped online gaming for years to come.
