Spin your ring.
Hold the line.
You are the Core. Spin a growing ring of turret shapes, chain upgrades into a dream build, and never let the swarm touch you.
Aim with one thumb
Drag anywhere and the ring of turrets follows your finger. Turrets at the front deal bonus Focus damage.
Every kill pays
Coins drop for each shatter. Spend them between waves on new turrets, upgrades, and repairs.
Trigger the Nova
A shockwave from the Core clears your lane in a pinch. Time it, then build it back up.
Chase the high score
Escalating waves, a boss every five rounds, and stats that all live on your device.
The Arsenal
Eight turret shapes to mix and master
Fast bolts, piercing pillars, instant beams, ricochets, area pulses, and splash mortars. Build the dream loadout, then sell and reroll for a new one.
How it works
Three things to master a run
Drag to aim
Rotate the turret ring toward the swarm to stack Focus hits. Turrets at the back barely fire.
Build between waves
Coins drop from kills and clears. Buy turrets, chain upgrades, or sell and reroll for a fresh plan.
Stay alive
Every wave grows meaner and a boss arrives every fifth. Chase the score, then do it again.
