About Krunker.io
Krunker.io is a fast, blocky first-person shooter that runs in your browser. Matches drop you into small maps with other players from around the world, and the action is quick: short respawns, sliding, bunny-hopping and a lot of movement.
You choose a class, such as an assault rifle, sniper or shotgun loadout, and each one plays differently. You earn rewards as you play and can customise your character and weapons with skins.
How to Play
- W A S D: move, Space: jump
- Mouse: aim, left click: shoot, right click: aim down sights
- R: reload, Shift: crouch (crouch while running to slide)
On a phone, use the game’s on-screen controls if they appear. Landscape orientation gives the player more room.
Tips for Krunker.io
- Keep moving. Standing still makes you an easy target.
- Slide around corners to enter fights faster.
- Try a few classes. Many players find one that fits their aim much better than the default.
Krunker Guide: Best Class for Beginners and How to Improve
Krunker is fast and movement-heavy. This guide explains which class to start with, how the main classes differ and what to practise to get better.
Read the full guide
1. Best class for beginners: Triggerman
Triggerman uses an assault rifle that works at every range. It is the default class and the one most guides, including Krunker's own, recommend for new players. Learn the game with it before trying the specialised classes.
2. Other common classes
The class list changes over time, so check the in-game menu for the current options.
- Hunter: a sniper class for players with precise, long-range aim.
- Run N Gun: fast movement with an SMG, best for close fights and aggressive play.
- Spray N Pray: high health and a heavy weapon, good for holding an area.
3. Movement is half the game
Krunker lets you slide, jump and bunny hop to move faster than running. Crouching while you run starts a slide, and chaining jumps keeps your speed up. It takes practice, so spend a few matches focusing only on moving well.
4. Simple habits that win more fights
- Keep moving while you shoot. A player standing still is the easiest target.
- Reload behind cover, not in the open.
- Lower your mouse sensitivity if you keep over-aiming.
- Play with friends in a private game to practise without pressure.
