All Krunker.io Classes Complete Guide

Krunker.io has 13 different classes, each with a unique weapon and playstyle. Here are all the classes explained:

Triggerman: The default assault rifle class. Fully automatic weapon with balanced damage and range. Best starting class for all new players who are still learning maps and movement.
Agent: Semi-automatic pistol class with the highest movement speed in the game. Low damage per shot but extremely fast and hard to hit. Best for experienced players who rely on movement to survive.
Spray and Pray: SMG class with the highest fire rate of any weapon. Devastating at close range but very inaccurate at medium and long range. Best for aggressive players who push close to opponents constantly.
Detective: Revolver class with serious damage per shot and medium fire rate. Strong at medium range with good accuracy. A balanced choice between the precision of a sniper and the speed of an SMG.
Marksman: Sniper rifle class with the most serious damage of any weapon. One-shot kill to the head at any range, but very slow between shots and requires precise aim. Best for patient players who hold sightlines.
Hunter: Shotgun class with massive close-range damage. Can one-shot opponents at point-blank range, but is completely useless beyond 10 meters. Best for small, close-quarters maps with tight corridors.
Run N Gun: Minigun class with continuous fire at the cost of accuracy. Best for suppressing enemies in open areas rather than precise gunfights.
Vince: Rocket launcher class with area-of-effect splash damage. Capable of hitting multiple enemies simultaneously. Requires leading shots to hit moving targets. Best for chokepoints and grouped enemies.
Bowman: Bow and arrow class with the most satisfying one-shot mechanic in the game. Arrows arc over long distances, requiring aim compensation. Very high skill ceiling and massive reward when mastered.
Rocketeer: Secondary rocket launcher class focused on mobility through rocket-jumping. Launch a rocket at your own feet to fly across the map at high speed. Extremely advanced class only recommended for experienced players.
Grenadier: Grenade launcher class for area control. Launches bouncing grenades that explode on contact with players. Best used in corridors and stairwells where grenades cannot miss.
Commando: Machine gun class with a built-in shield ability. Hold right-click to raise a bulletproof shield that blocks all incoming fire while moving at reduced speed. Unique defensive playstyle unlike any other class.
Infected: Close-range melee class from special infection game modes where infected players must spread to uninfected humans through contact. Most damage is dealt by getting physically close to opponents.

Top Pro Strategies to Win Every Krunker.io Match

Strategy 1: Master Bunny Hopping First

Bunny hopping, jumping repeatedly while moving, is the single most important skill in all of Krunker.io. Players who bunny hop are significantly harder to hit than players who walk normally.

Hold W, press the spacebar repeatedly, and practice maintaining your speed through every corridor and open area.

Strategy 2: Always Strafe During Gunfights

Never stand still during a gunfight. Press A and D alternately while shooting to strafe unpredictably left and right.

Strafing correctly cuts incoming damage by 40 to 60 percent compared to standing still and makes you dramatically harder to kill in every engagement.

Strategy 3: Control the High Ground

Every Krunker map has elevated positions, rooftops, platforms, and raised corridors that provide better sightlines and natural cover advantages.

Identify and control the highest position on each map before enemies do, and you will consistently outscore players with equal aim ability.

Strategy 4: Headshots Win Every Engagement

Krunker.io deals roughly double damage for headshots compared to body shots with most classes. Keep your crosshair at the precise height of enemy heads as you move around each map. Every headshot you land shortens the time-to-kill dramatically versus body shots.

Strategy 5: Learn Three Maps Before Playing Others

Krunker has hundreds of maps, but mastering three specific maps, completely knowing every corner, every angle, every spawn, every jump, gives you a massive structural advantage over players who play randomly on all maps without deep knowledge of any single one.

Strategy 6: Use Slides Offensively

Pressing Shift while running activates a slide that briefly makes you a much smaller and faster target. Use slides aggressively when entering rooms, rounding corners, and closing distance on opponents.

Players who slide into gunfights consistently win more engagements than players who walk normally.

Krunker.io Game Modes Explained

Free For All: Every player for themselves. Most kills win. Best mode for practicing individual aim and movement without team pressure.
Team Deathmatch: Two teams compete for the highest combined kill count. Requires basic coordination and map rotation to consistently win.
Hardpoint: Teams capture and hold a single rotating objective point to earn score. The most strategically complex default mode requires both combat skill and objective awareness.
Capture the Flag: Each team must steal the opponent’s flag and return it to their base. Requires dedicated attackers and defenders working in coordination.
Infected: One infected player must spread infection through melee contact. Uninfected players must survive until the timer ends. A unique mode that plays nothing like standard FPS gameplay.
Custom Maps: Community-created maps with custom rules, themes, and game modes. The most diverse content in Krunker available entirely through the community map browser.

Shell Shockers Unblocked: Egg-themed FPS with 7 weapons and 4 modes. Easier to learn than Krunker and more humorous in presentation. Better for players who want casual competitive play without a deep class system.
1v1 LOL Unblocked: Building and shooting with a single opponent. More strategic than Krunker due to construction mechanics but less fast-paced in moment-to-moment gunfights.
