Krunker.io review

Krunker.io takes first place because it packs the most game into a browser tab. The site calls itself a free online multiplayer FPS with no download required that works on any device, and the menus show how far it goes beyond a simple arena: classes such as Agent and Stalker, a Krunker Competitive ranked queue, spectator tools with free camera and objective camera, and a prop hunt style mode with taunts. A separate Game Editor lets players build custom maps with spawn points, objects and entities, and the Krunker Hub adds clans, a player market, trading and giveaways. Money goes to KR, the in-game currency, which the store sells through Apple Pay, Google Pay and other methods for cosmetics. The trade-offs are a steep skill curve, since matches are fast and aim matters, plus ads and a consent wall before the first game. We compared documented features and published prices; we did not measure match quality.
