This collection groups first-person shooter and first-person movement projects from the Radiant Optimizer source list. It includes Zombies, Halo, Quake, Wolfenstein, Half-Life, and related community browser work.
An FPS label describes the source title or project type. It does not mean every destination is live, complete, official, or playable without files from a copy you own.
Open the guide before the external project. Confirm its status, owned-file requirement, browser notes, and controls instead of assuming every FPS entry starts the same way.
Cards retain the source-led status and requirement labels used across the complete directory.
