There are many popular Roblox FPS games like PF, Arsenal, Notoriety, Entry Point, Randomizer, TC2, Bad Buisness, and more. There are also less known ones like Caliber, Doomspire Portals, Aimblox, and Energy Assault. I think any Roblox game under the FPS genre should have event clips like kills, wins, and killstreaks.
