Krunker: Beginner-to-Advanced Guide

A practical guide to Krunker, the fast browser/client FPS: movement tech (slidehopping first), classes and loadouts, settings for high FPS, the economy, ranked play, and custom games.

Researched September 2026 — current as of the latest Krunker patch notes published on Steam (client 3.0.0, February 2022); newer in-game seasons are announced on krunker.io and weren't verifiable for this guide. Live games change; check the linked sources if something differs.

Where to play: Krunker runs in the browser at krunker.io and through the official client, including the Steam version (developer/publisher listed as FRVR). The Steam client requires a Krunker account and supports Windows and Mac. The Steam news feed hasn't been updated since February 2022, so follow the in-game changelog for current season details.

Quick Start

Learn to slidehop on day one. Jump while holding forward, then hold crouch as you land to slide, and repeat. It's the core of Krunker movement and works on every class.
Strafe constantly. Pressing A/D while shooting makes you much harder to hit. Standing still is how you die in Krunker.
Start with an easy-to-aim class. An automatic weapon (assault rifle, SMG or LMG) is more forgiving than sniper or revolver while you learn movement.
Uncap your FPS and lower visual effects. Krunker is a browser-engine game; performance settings matter more than in most shooters (see Settings below).
Pubs rotate through a set of 12 rotation maps. Learn a few power positions and routes on each; map knowledge beats aim in pubs.
A "nuke" is 25 kills without dying. It's the classic flex — and you'll get more of them by holding strong positions than by roaming.
Don't leave matches early. Leaving counts as a loss and a death on your stats.
Custom games are half the game. Parkour, Infected, CTF and thousands of community modes are in the server browser — great for practicing movement.

Movement (the skill that matters most)

Technique	How	Notes
Strafing	Hold A or D while aiming	The base of dodging; combine with jumping
Slidehop	Jump holding W, hold crouch on landing to slide, jump again at the end of the slide	"Easy to learn, hard to master"; timing the next jump keeps speed
Walljump	Run into a wall, press against it, jump	Behavior has changed across updates; test it on a Parkour map with your class
Ramp slides	Slide down slopes to build speed	Maps have ramps placed for this; learn them
Rocket jumps	Rocketeer can boost with its launcher	Precise timing required

Practice routine:

Load a Parkour custom game and slidehop through it until it feels automatic.
Practice sliding around corners into a fight — a slide changes your hitbox and speed at the moment you peek.
Mix jumps into strafes so you don't move in a predictable line.

Classes

Krunker's class sets your primary weapon and some movement/health traits, and each class levels separately (Double Class XP weekends run every other weekend, per the Season 5 update). The long-standing core roster is below (Triggerman's AK, Agent and Runner are named in the 2021 patch notes; the rest reflect the classic roster and weren't re-checked against the current in-game menu). The game has added, renamed and rebalanced classes over time, so check the class menu for current weapons and stats.

Class	Primary weapon	Good for
Triggerman	Assault rifle (AK)	Best all-rounder for beginners
Hunter	Sniper rifle	Quick-scoping; highest skill ceiling
Run N Gun	SMG	Aggressive movement
Spray N Pray	LMG	Holding angles with a big magazine
Vince	Shotgun	Close-quarters maps
Detective	Revolver	Precision duelling
Marksman	Semi-automatic rifle	Mid-range tap shooting
Rocketeer	Rocket launcher	Splash damage; rocket jumps
Agent	Dual SMGs	Close range; banned from competitive in 2021
Runner	Melee	Movement-focused; banned from competitive in 2021
Bowman	Crossbow	Projectile precision
Commando	Burst rifle	Mid-range bursts

Which to pick:

New players: Triggerman or Spray N Pray — forgiving automatics.
Aggressive movers: Run N Gun.
Aim-focused players: Hunter (quick-scopes) or Detective.
Competitive: check the current comp ban list; as of the 2021 patch notes Agent and Runner were removed from comp matches and the Alien Blaster weapon was banned.

Gunfight Fundamentals

Krunker's time-to-kill is short and everyone moves fast, so small habits decide most duels.

Habit	Why it wins fights
Reload behind cover, not mid-lane	Reloads are long enough to lose a duel; the 2021 patch notes even slowed the AK's reload
Pre-aim at head height around corners	Your crosshair should already be where an enemy will appear when you peek
Aim for the head with precision weapons	Sniper, revolver and semi-auto reward headshots far more than body shots
Swap to your secondary instead of reloading when a fight is close	It's usually faster than finishing a reload
Fight from the edge of your weapon's best range	Automatic weapons lose accuracy at long range; snipers struggle up close
Use height	Dropping onto enemies from above, or sliding off ramps into them, makes you harder to track

Reading the scoreboard: in pubs, the players at the top are usually holding a power position. Find where they're shooting from and either avoid that sightline or flank it, rather than peeking the same angle repeatedly.

Warm-up routine (10 minutes): a few minutes of slidehopping on a Parkour map, a few minutes in an FFA custom game with your main class, then queue. Movement first, aim second.

Maps and Modes

Public matches cycle through 12 rotation maps. Since Season 5, the fourth map in a pub rotation is always a unique mode (for example a raid or party mode).
Modes include Free for All, Team Deathmatch-style modes, Capture the Flag, Infected, Parkour and many custom modes made with the map editor and KrunkScript.
Raids and events appear as official events (Season 5 added a raid event called Tortuga).
Custom servers can be hosted from the server browser in a couple of clicks.

Map tips:

Learn the high ground and long sightlines on each rotation map; snipers and LMGs control those.
Learn where the ramps are — they're built for slide speed.
On objective modes, movement lets you rotate faster than anyone who walks.

Settings for Performance and Clarity

These come from a popular community "Best Settings" guide. They're a starting point, not rules.

Setting	Suggested	Why
FPS cap	Uncapped (client)	Lower input latency
Particles, shadows, ambient shading, trails, muzzle flash, casings, impact holes	Off	Big FPS gains; less visual noise
Post-processing / lighting	Off	FPS
Resolution scale	Lower if your FPS is unstable	Browser engine is CPU-sensitive
Field of view	Around 110	More awareness
Weapon bob	Low	Steadier view
Crosshair	Custom, high-contrast	Visibility
Screen shake	Off if flinch bothers you	Season 5 added a small damage flinch that can be disabled via screen shake
Master volume	Moderate, with gunfire and footsteps audible	Audio cues matter

Sensitivity: use the lowest sensitivity you can still turn around comfortably with. Krunker's pace tempts you to go high; lower sensitivity helps tracking.

Client extras: the official client supports resource packs (added in client 3.0.0) and a resource swapper for custom textures/sounds.

Economy and Progression

Item	What it is
KR	The main currency; buy with money or earn in-game, spend on spins, items and market trades
Junk	Added in Season 5; dissolve skins into Junk and spend it at the Junkyard to craft items
Materials	Can spawn around pub maps; used in crafting (dropping a nuke has a small chance to drop uranium)
Spins	Loot rolls for skins; odds vary by rarity
Market	Buy, sell and trade skins with other players
Challenges	Daily, map-specific and weapon-specific challenges with rewards
Badges	Profile badges from challenges and milestones

F2P tips:

Do daily challenges — they're the steadiest free rewards.
Don't gamble KR on spins if you want a specific skin; buying directly on the market is usually more reliable.
Dissolve duplicates into Junk rather than letting them rot.
Cosmetics don't affect gameplay; spend nothing until you know you'll stick around.

Ranked and Competitive

Krunker has official ranked play and FACEIT integration (added to the client in November 2021).
Competitive rules differ from pubs: some classes and weapons are banned (see above), so practice with comp-legal loadouts.
Anti-cheat and moderation: the Krunker Police Department (KPD) handles reports; your trust score affects your ability to call KPD.

Common Mistakes to Avoid

Walking. If you're not sliding or strafing, you're a free kill.
Running Hunter before your movement is solid. Sniping in Krunker relies on repositioning.
Leaving matches early. It records a loss and a death.
High graphics settings. Dropped frames cost more gunfights than a lack of shadows ever will.
Chasing a nuke by roaming. Hold a good position and let enemies come.
Spending real money early. Cosmetics only.

Advanced Tips

Slide-peek: slide around a corner instead of walking out; your speed and lowered hitbox win first shots.
Jump-shot timing: test your main weapon's accuracy while moving and airborne in a private custom game, and learn when to land before firing.
Quick-scoping (Hunter): the pub staple; practice scope-in flicks in an FFA or aim-training custom game before taking it into ranked.
Sound whoring: footsteps and reloads give positions away — keep gun volume below footstep volume.
Rotate between power positions after every couple of kills to avoid being pre-aimed.
Use custom games to train: Parkour for movement, FFA for aim, and KrunkScript-made aim trainers where available.
