About the game

Real-time space strategy: command a capital ship in 3v3 online fleet combat.

Original Steam 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
