Best browser FPS games
Real multiplayer shooters that run in a browser tab — no installs. These are live services, so they play on their official sites; every button below is the game's own address. List verified 2026-10-15.
Krunker.io
The biggest browser FPS by a wide margin: blisteringly fast movement, slide-hopping, dozens of classes and a giant library of community maps and mods.
Play on the official site →Shell Shockers
You are an egg. You have a gun. Under the joke is a genuinely tight arena FPS with loadouts, multiple modes and instant matches.
Play on the official site →Venge.io
Objective-based FPS with hero characters, ability cards and unlockable skins — closer to a hero shooter than a bare-bones .io game.
Play on the official site →Repuls.io
Sci-fi arena FPS with vehicles, tanks, mechs and a grappling hook — the most feature-heavy of the browser-native shooters.
Play on the official site →Combat Online
NAD Games' long-running browser FPS (the studio behind Combat Reloaded) — classic Counter-Strike-flavoured maps and modes, playable from the publisher's own site.
Play on the official site →Voxiom.io & Narrow.One
Both are shooters at heart and both sit in our Battle Royale section: Voxiom.io mixes voxel building with gunplay; Narrow.One is pure bow-and-arrow castle combat.
Voxiom.io → Narrow.One →How this guide works: GAMEHUB only lists games at their official addresses, and labels every one honestly. No mirrors, no "unblocked" copies, no fake player counts.
