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

ObbloxGun.io is a blocky first-person shooter built for short arena matches — join, fight, unlock a gun, repeat. Matches are quick enough to fit into a break, coins accumulate across sessions, and the whole thing runs in a browser tab without an account.

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.

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.
