About this game

The Breakers are coming for the last energy core, and they never stop circling.

Core Breakers is a portrait defense game you play with one finger. Eight turrets sit in a ring around your core. Drag the ring to turn it, and point your firepower at the side where the swarm is breaking through. You don't have to spin to clear the first sector, but a good spin is how you go further.

SPIN THE RING
• A rush alert tells you which side is about to erupt. Turn the ring in time and meet it head on
• Every enemy that slips past the gate costs you life, then comes round again stronger and faster
• Ride out every wave and take down the boss at wave 30

MERGE AND BUILD
• Summon turrets with gold and merge two of the same into a stronger one, up to ★3
• Six turrets, each with its own job: Vulcan, Heavy Cannon, Mortar, Guardian, Drone Hub and Railgun
• Every five waves, pick one of three core modules: shockwaves, chain lightning, critical hits and more
• When all seems lost, hold the Core Break button to clear the screen once per run, at a price

KEEP GOING
• Three sectors of 30 waves each, with their own twist and their own boss
• Threat levels 1 to 10 for every sector you clear, adding a new rule every other level
• A new daily condition and three daily missions to try every day
• Permanent upgrades for your turrets and core, unlocked further as you clear sectors

FAIR AND OFFLINE
• No forced ads. Ads only play when you tap a reward button, and they are always optional
• Summon odds are shown on the button and in the codex
• Plays offline, no account needed
• Progress is saved on this device. Use Backup Code to move devices.
• English and Korean

Purchases are optional. They never sell random rewards, and upgrade levels are capped by the sectors and threat levels you have cleared, so progress always comes from play.
