The official Quake II demo (1997) — Unit 1 of the singleplayer campaign against the cybernetic Strogg aliens. Fight through interconnected, mission-based levels with the id Tech 2 engine's colored dynamic lighting.
About
Released December 9, 1997, developed by a 13-person team at id Software and published by Activision. Quake II shifted from its predecessor's Lovecraftian horror to a sci-fi military campaign against the Strogg — a cybernetic alien race that harvests and assimilates other species. The id Tech 2 engine introduced colored dynamic lighting and a hub-based level structure where you revisit areas with new keys and equipment.
The demo includes Unit 1 of the singleplayer campaign, featuring mouselook, crouch, and reload mechanics. It entered PC Data's monthly sales chart at #2 for December 1997, behind only Riven. id Software released the full Quake II source code under GPL in 2001. This runs on Yamagi Quake II compiled to WebAssembly.

- Crouch for vents — Use crouch to access vents and low passages hiding secrets and shortcuts.
- Weapon effectiveness varies — Different weapons are more effective against different Strogg types. Experiment.
- Colored lighting = danger — The colored dynamic lighting often signals combat areas and ambushes.
- Reload during quiet moments — Don't get caught in a firefight with an empty magazine.
Did You Know?
- The name "Quake II" was almost "Wor" — legal concerns over other title candidates led the team to reuse the Quake name, despite the sequel having zero narrative connection to the original.
- id Software released the Quake II source code under GPL in 2001, leading to dozens of enhanced source ports including Yamagi Quake II used here.
- This was the last id Software game to feature American McGee, who was fired shortly after its release and went on to create Alice: Madness Returns.
