AIM. MULTIPLY. DESTROY!
A castle siege on tank tracks. Pull back to aim, fire through gates that turn three rockets into hundreds, and tear the enemy fortress down floor by floor.
Drag back anywhere on the battlefield and let go. Time it so the salvo flies through ×10, or even the golden ×50.
ONE DRAG. ONE BOOM.
HUNDREDS OF ROCKETS.
AIM.
Touch the battlefield anywhere, pull back like a slingshot and let go. The dotted line shows how your arc begins.
MULTIPLY.
Fire through the gates floating in the gap. ×2, ×10, even ×50 clone every missile; dodge the −5 and ÷2 that eat them.
DESTROY!
Craters carve the hills, floors collapse, turrets tumble off and tank treads go up in a fireball.
THE GATES
ONE ROCKET BECOMES A STORM
Every gate a missile flies through changes the count. Six hundred fly at once and the rest fold into the swarm, so even a salvo of thousands lands with exact damage.
ONE BURST LEAVES THE TURRET
3
30
1,500
Three rockets fired through a ×10 gate become 30, and through a ×50 gate after that, 1,500.
GATES THAT HELP
GATES THAT HURT
Hazard stripes, so colour is never the only warning.
Gates bob, slide and orbit on a clock both players share, so timing your release beats raw power. Gate Freeze stops them for a turn.
FULLY DESTRUCTIBLE
WATCH IT ALL COME DOWN
Every hit bites a chunk out of the wall it lands on and sends bricks flying.- Floors shatter into rubble, the ones above drop with a thud, and turrets pop off and blow up where they land.
- Craters carve the hills and glow as they cool; ledges cut loose break away and fall, castle and all.
- The killing blow sets off a chain of blasts and a shockwave before the VICTORY ribbon rolls in.
THE ARSENAL
FOUR WEAPONS. FIVE PERKS.
One weapon per turret, each upgraded through five levels with coins and blueprints. Pack up to three perks in your loadout and use one per turn.
ROCKETS
From the start
Unlimited bursts of 3 to 5. The best friend of a ×50 gate.
CLUSTER BOMB
After level 1-3
Splits into 5 to 9 bomblets at the top of its arc.
HEAVY MORTAR
After level 1-10
One slow, heavy shell that blasts huge craters.
LASER
After level 2-10
A straight beam that pierces terrain, ignores the gates and half the armor.
SHIELDA 120-HP bubble absorbs damage until it breaks.
GATE FREEZEThe gates stop moving for your turn.

Touch the battlefield anywhere, pull back like a slingshot and let go. The shot flies opposite to your drag, and the length of the drag sets the power. Send the salvo through the gates floating in the gap to multiply it, then watch it bring the enemy castle down.
