ObbloxGun.io — Free 3D Block FPS in Your Browser

What makes it different

It sits in the gap between the very light .io shooters that are basically top-down and the heavy browser FPS games that take a minute to load. Movement is simple, maps are small, and time-to-first-fight is a few seconds.

Controls

Left mouse button	Shoot

Tips that actually help

• Strafe while shooting. Standing still to line up a shot is the single biggest killer in small arenas — blocky hitboxes are generous enough that moving fire still lands.
• Learn one map corner properly rather than roaming. Quick-match maps funnel players through the same two or three routes, and holding one of them out-earns wandering.
• Spend coins on a gun you already aim well with. A higher-damage weapon with a firing pattern you cannot control is a downgrade in practice.
• On mobile, auto-aim handles targeting but not positioning — your job becomes movement and cover, not aiming.
• Reload during the walk back to the fight, never in it. There is no reload cancel, so a mid-fight reload is usually a death.

FAQ

Is ObbloxGun.io free?

Yes, it is free and ad-supported, playable in the browser with no account.

Do I play against real people?

Matches are online multiplayer arenas, so you are matched with other players currently in the game.

Does progress carry over between sessions?

Coins and unlocked weapons persist in your browser. Clearing site data or switching browser will reset them.

Is there auto-aim on desktop?

No. Auto-aim and auto-fire are mobile-only concessions to touch controls.

Why does the first load take longer than later ones?

The 3D assets are cached after the first load, so returning to the game is noticeably faster.
