Kour.io is a free online .io FPS developed by Legion Platforms, released in March 2024. It stands out from other browser shooters because of its class system — each of the 13 characters carries a different primary weapon with distinct HP values, meaning class selection directly shapes how you engage in every firefight. A 150 HP Heavy with a machine gun plays nothing like a 80 HP Recon running a Vector submachine gun, and recognizing which class suits a given map and mode is half the battle.
The game offers seven official modes ranging from Free For All and Team Deathmatch to more unusual options like MoonSnipe (low-gravity sniping) and KourSurf (surfing combined with shooting). A built-in map editor lets players create custom arenas, and community-created modes like KourCraft expand the experience further. Progression runs on KP (Kour Points), earned through kills and missions, which unlock cosmetics, crates, and emotes. Clan support and daily, monthly, and all-time leaderboards give long-term players a competitive ladder to chase. As an HTML5 game, it loads directly in your browser on both desktop and mobile.
Move with WASD, jump with Space, and shoot with Left-click. Aim down sights using Right-click for tighter accuracy at range. Crouch with Shift or C to reduce your profile and improve stability. Press E to dash — a short burst of lateral movement useful for dodging or closing distance. Switch between your primary, secondary, and melee weapons with 1, 2, and 3. Press B to emote and F to inspect your weapon. The Esc key opens the pause menu.
Your immediate goal in most modes is straightforward: get kills. In Free For All, the player with the most kills wins. In Team Deathmatch, your kills contribute to your team's combined score. Hardpoint adds a territorial twist — teams fight over a control zone on the map, earning points both from kills and from occupying the zone. Gun Game forces you through a preset sequence of weapons, advancing to the next gun with each kill. Across all modes, kills and completed missions earn KP, which feeds into your overall level and unlock progression.
Class selection happens before spawning. Nine classes are available immediately, and four more unlock after reaching 10 kills in a session. Each class carries a unique primary weapon and has a fixed HP pool. The Soldier (AK-47, 100 HP) is the most versatile starting pick — accurate at medium range with a solid health pool. The Hitman (Sniper Rifle, 90 HP) excels on open sightlines but struggles in close quarters. The Heavy (Machine Gun, 150 HP) absorbs punishment but moves slower and has less precision. Understanding these tradeoffs — and switching classes between deaths when a matchup isn't working — is a core skill that separates experienced players from new ones.
KP accumulates across matches and ties into your account level. Higher levels unlock access to cosmetic items including skins, hats, characters, and emotes. You can also earn crates containing random cosmetics. The leaderboard tracks performance on daily, monthly, and all-time scales, and joining or creating a clan lets you coordinate with regular teammates. The map editor provides a creative outlet — build a custom arena and host matches on it through the server finder.
Havana's tight corridors and rooftops favor close-range classes like the Brawler (Shotgun) and Agent (Silenced MP5). Ghost Town's open desert sightlines reward the Hitman's sniper rifle. Snowstorm's mix of elevation and open space benefits versatile picks like the Soldier or Assassin (FAMAS). Before spawning, consider the map layout — picking a sniper on a cramped indoor map wastes the weapon's primary advantage.
Pressing E gives you a quick movement burst. Most beginners use it to rush toward enemies, which often puts them in the middle of a firefight with the dash on cooldown. Instead, save your dash for escaping after a failed push or sidestepping when an enemy catches you in the open. A defensive dash that keeps you alive is worth more than an aggressive one that gets you killed two seconds faster.
Holding Shift or C drops your profile and improves weapon stability. When approaching a corner where an enemy might be holding an angle, crouching and strafing into the sightline gives you a smaller target and better accuracy on your first shot. Running full speed around a corner hands the advantage to whoever is already aiming there.
Not all fights are even. If you're a 90 HP Recon and you walk into a 150 HP Heavy in a hallway, the Heavy has a nearly 70% health advantage before either player fires a shot. Knowing the HP values of common classes tells you which fights to take head-on and which to disengage from. Against high-HP targets, chip damage from cover or flanking routes wins more reliably than a direct shootout.
The AK-47, FAMAS, and Sniper Rifle reward headshot accuracy significantly. Body shots from a sniper may not kill a full-health target in one shot, but a headshot often will. If your chosen class uses a single-fire or burst weapon, spend the extra fraction of a second aiming at head level. On automatic weapons like the P90 or Machine Gun, spray patterns start high, so beginning your burst aimed at chest level naturally walks rounds into headshot territory.
Some maps contain green laser zones that grant a temporary speed boost when you walk through them. Use these intentionally rather than stumbling into them — knowing their locations on each map lets you time rotations faster, reach Hardpoint zones before the enemy team, or escape after a kill streak when your health is low.
Getting 10 kills in a session unlocks Juggernaut (Minigun), Recon (Vector), Pyro (Flamethrower), and Rayblader (Laser Gun). These four classes offer specialized tools that the base roster doesn't cover — the Pyro's flamethrower dominates tight spaces, and the Rayblader's laser provides a unique damage profile. Push for 10 kills early in your session to access the full class roster for the rest of your play time.
