CatWars.io is a free browser-based 2D top-down survival action game. You play a brave little cat fighting endless waves of dogs across an open map. Hunt food to gain experience, evolve through 50 distinct levels (from a tiny Kitten all the way up to a mythical God Cat), unlock weapons and helmets in the Codex, and survive as long as you can.
The game runs entirely in your browser — there is nothing to install. You can play instantly as a guest, or sign in with an account (e‑mail or Google) to save your progress to the cloud and appear on the public leaderboards.
Gems are CatWars' permanent currency. You spend them in the Codex (Encyclopedia) on permanent weapon upgrades, helmet bonuses, daily quests and active boosts. Boosts can be equipped before a run for in‑match bonuses such as extra damage, faster pickup, more gems or a shield.
The Daily Spin gives you a free reward every 24 hours, and chests scattered across the map drop additional gems and food. There is no pay‑to‑win — all progression is earned through play.
