About game
Defend the last living planet from an endless swarm. Shoot enemies down and forge orbital defenses from their debris — merge three into one: turrets, lasers, shields, stations, up to legendary citadels and arks. The further you push, the stronger your next run starts: gems boost you permanently. Planet defense, merge and roguelite in one.
How to play
The planet fires on its own — your job is to make the defense stronger. In battle: tap enemies for a precise shot, charge the orbital strike and unleash it when the ring lights up, spend XP on attack, defense and economy upgrades. Between waves comes the shipyard: merge three identical debris pieces into a higher-tier item, and place buildings (tier 3+) into orbit slots — turrets, lasers, shields and stations will fight for you. If a landing ship breaks through, build your garrison: hire troops for gold and merge identical ones into stronger fighters. Survive 30 waves to hold the Frontier, then push records in endless mode. Spend gems on permanent upgrades and relics — every next run starts stronger.
