Cooldown MMO is a free browser fantasy MMO. No download: create an account and play in the browser.

Each move, fight, gather, craft, bank, or dungeon pull is one server action with a cooldown. The server resolves combat, loot, and cooldowns. Weapons and armor come from crafting and starters, not random combat drops.

Two overworld maps are live — Sunveld and Amberfall — with ferry travel between them. Fight solo or in parties, run dungeon waves, tackle world bosses, take quests, send champions on expeditions, spend talent points, earn faction standing at hub shrines, and unlock mounts.

The Looper is a built-in command deck that chains fight, gather, travel, bank, craft, vendor, quest, and shrine steps under the same rules as clicking in the UI. Developers can drive the same REST API with a Bearer token.

Public encyclopedia, leaderboards, speedrun boards, and champion profiles are open without installing anything.
