Build the strongest fortress and blast the enemy to rubble!

Fort Star is an idle fortress battle game where your castle does the fighting. Collect powerful weapons, mount them on your fort, and watch it wage war on rival castles in spectacular automated battles. Every fight ends the same way: one fortress in ruins. Make sure it is not yours.

Your fortress workshop keeps producing while you are away, so there is always idle cash waiting to grow your arsenal when you come back.

ARM YOUR FORTRESS
Collect miniguns, cannons, rockets and mortars, each with its own firing style: spraying bullets, arcing mortar shells, wobbling rockets with splash damage. Merge duplicate weapons to power them up and roll rare drops to build the ultimate war machine.

POSITION IS EVERYTHING
Your castle is a real structure: the front wall shields what stands behind it, the roof shields what sits below, and your core hides deep inside. Choose your mounts and reorder your weapons to protect your core and expose theirs. Defense costs firepower: shield generators and repair drones each take a weapon slot, so every loadout is a strategic call.

WATCH TOTAL DESTRUCTION
Battles run on their own: your weapons pick targets and fire while cannonballs crack walls, rockets blow rooms apart, and shattered cells come crashing down. Damage keeps escalating until one core dies, so no fight ever ends in a draw. Blow up the enemy core and watch the whole castle collapse in a fireworks finale.

CLIMB THE LEAGUES, GROW YOUR CASTLE
Fight your way through 10 leagues, and watch your fortress physically grow with every promotion: bigger walls, more weapon mounts, more chaos. Win battles, earn trophies, and build your reputation as the last fort standing.

GEAR AND UPGRADES
Equip your weapons with powerful gear, boost your fort's total damage and health, and watch every single mounted weapon hit harder with each upgrade.

EARN WHILE YOU ARE AWAY (IDLE PROGRESSION)
Your fortress keeps generating income even when the game is closed, with offline earnings waiting for you. Check in, collect your cash, upgrade your arsenal, and roll out for the next siege.

SEASON PASS AND DAILY REWARDS
Climb the Season Pass and grab daily rewards that keep your armory growing every day.
