Keep Shift
THEY WANT YOUR THRONE.
GIVE THEM HELL.
Your castle is under siege, but its walls hide something unusual: every trap room can move. Rearrange the castle around your enemies, unleash deadly combinations, and survive five waves of increasingly dangerous invaders.
A CASTLE THAT FIGHTS BACK
Why build defenses when you can move the entire battlefield?
In Keep Shift, you control four magical trap chambers inside a besieged castle. Swap their positions to ambush enemies, set up combinations, and stop invaders before they reach your throne.
Every room has its own ability and cooldown. The trick isn't just knowing which trap to use. It's knowing when and where to move it.
FOUR ROOMS. ENDLESS TROUBLE.
THE INFERNO
Set your enemies ablaze. Burn damage continues even after they leave the room.
THE FREEZER
Stop enemies in their tracks. Freeze an entire group and create an opening for your next trap.
THE CRUSHER
A brutal burst of area damage. Time your swaps to catch as many invaders as possible.
THE BARRAGE
Target the enemy closest to your throne with a powerful volley of arrows.
SHIFT. STRIKE. REPEAT.
WATCH THE SIEGE
Invaders enter from the bottom and climb toward your throne. Keep an eye on their positions and your available traps.
SWAP YOUR ROOMS
Drag one trap chamber onto another to exchange their positions. Alternatively, tap one room and then another.
TIME YOUR ATTACKS
Every room has a cooldown. Catch enemies inside your traps and combine their effects for maximum damage.
HOLD THE THRONE
Survive five waves, choose upgrades between attacks, and stop the final boss before your throne is destroyed.
