Krunker.io is the browser shooter that plays like a real one. Sidney de Vries released it in 2018 as a voxel-styled, low-spec FPS that runs in a tab, and it grew into a game with its own competitive scene: twelve classes with distinct weapons, a movement system built around slide-hopping to keep momentum, custom games, a map editor and a skin market.
It is deliberately lightweight — the blocky art exists so the frame rate stays high on weak hardware — which is exactly why it became the FPS of choice on school laptops. No account is needed to play; one saves your progress and unlocks.
No. You can play as a guest immediately. An account saves your level, KR and skins, and is needed for ranked and custom lobbies.
Sliding (Shift while moving) and then jumping repeatedly to keep the momentum from the slide. It is the core movement technique and the main thing separating new players from good ones.
Yes — it was built for low-spec browsers and runs well on Chromebooks with nothing to install. Lower the graphics settings if the frame rate dips.
