Kirka IoKirka.io is a free voxel-style browser FPS with free-for-all, team, and capture-the-flag matches, plus a standalone parkour mode to test your movement.
Kirka Io
Kirka.io drops you into a blocky, voxel-style shooter that runs entirely in the browser — no download, no launcher, just a lobby and a gun. The low-poly look keeps enemies readable at a glance, which matters once a match turns into a scramble across rooftops and stairwells with three or four players converging on the same corner.
Matches are quick and match-made: free-for-all if you’d rather fight everyone at once, team deathmatch and capture the flag if you want to coordinate, and a separate parkour mode that strips the guns out entirely and turns the same maps into an obstacle course against the clock. Wins and losses earn gold, which goes toward chests for new skins and weapons rather than anything that changes how the guns actually handle.
Controls
- Move: WASD
- Jump: Space
- Shoot: Left-click
- Aim down sights: Right-click

Tips that actually help
- Aim down sights (right-click) tightens your spread noticeably — don’t hip-fire past close range.
- The dash (E) closes distance fast but leaves you briefly exposed on the way in; use it to reach cover or break a sightline, not mid-firefight.
- Jumping while you move makes you a harder target than walking in a straight line — worth practicing in an empty match before you take it into a ranked one.
- Nobody’s shooting at you in parkour mode, so it’s a low-stakes way to learn a map’s rooftops and angles before you rely on them in a real fight.
If the voxel look and fast movement click for you, Venge.io on this site is a similar low-poly browser FPS worth trying next.
