About

Cosmo Arena

Features
Read full description

Cosmo Arena is a real-time space strategy game where you command a single capital ship instead of an army. Pick your hull, take it into a contested system, and out-fly five other commanders in fast 3v3 online space combat. CHOOSE YOUR CAPITAL SHIP • Vindicator — heavy guns, heavier armour, and a Judgement Cannon that takes a fighter squadron off the board in one shot. • Sovereign — launch and command your own fighter wing while you hold the line from range. • Warden — feed shields to a dying ally, repair under fire, and keep a push alive that should have collapsed. • Juggernaut — the tank, lock down, dig in, and turn a corridor into a place nobody crosses. FIGHT, FARM, UPGRADE Every kill and every mineral field pays for the ship you become. Spend on weapons, shields, engines and hull, unlock abilities mid-match, and arrive at the late game as something the enemy fleet has to answer. REAL-TIME TACTICS, NOT UNIT SPAM • 3v3 multiplayer space battles against real commanders • A competitive ladder — every online match is rated • Full fleet control: your capital ship, your fighters, your interceptors • Skill-shot abilities: charge it, aim it, land it • Fog of war, outposts and lane control worth fighting over • Five AI difficulty levels for solo play while you learn the hulls BUILT FOR PHONE AND DESKTOP One account, one record, both devices. Touch controls designed for a phone in landscape — not a desktop interface shrunk down. Sign in with Google, Apple, or play as a guest and decide later. CROSS PLATFORM Cosmo Arena also runs in any browser at cosmoarena.co. Same servers, same account, same ladder — start a match on the phone, finish the evening on a monitor.
