## What is Alien Fortress?

Build a combat vehicle, recruit specialist gunners, and break into a secret fortress overrun by alien monsters.

Alien Fortress blends bullet-hell shooting, roguelite exploration, tower defense, real-time strategy and base management. Every mission asks you to adapt your chassis, weapons and operators to the battlefield, then punch through the enemy with firepower and smart positioning.

BUILD YOUR OWN COMBAT VEHICLE
Mix and match more than 10 distinctive mecha chassis with over 20 weapon operators. Each weapon has its own range, firing rhythm and tactical role. Deploy multiple vehicles together and turn a small squad into a wall of fire.

EXPLORE, LOOT AND GROW
Collect weapon parts, relics and equipment to upgrade your vehicles and operators. Eight companion pets provide different bonuses, giving every squad its own path to power.

45 STORY STAGES
Fight through mines, serpent caves, alien motherships, hives, aerial fortresses, dune strongholds, reactors and the Death Star. Defeat massive bosses and uncover a plan to harvest Earth’s civilization.

MORE WAYS TO PLAY
• Ladder Maze — randomized dungeon runs
• Outpost — endless defense
• Hive War and Dune Fortress — build-and-defend RTS battles
• Treasure Raiders — high-difficulty challenges
• Endless Swarm — mow down waves of alien creatures
• Whack-a-Mole — a quick arcade diversion

Drive, deploy, upgrade and improvise. Break out of every trap and lead your bounty hunters deeper into the alien fortress.
