Choose your weapon, survive 10 waves, defeat 3 bosses, and compete on daily and lifetime leaderboards. Every run is different. Fortress Auto Defense is a portrait mobile auto-defense game where your weapon fires automatically and your decisions decide the run. You do not move, aim, or manually shoot. Your defense gun stays at the bottom of the battlefield, enemies come from the top, and the system automatically targets and fires. Your job is to build the right weapon combination before the enemies break through. At the start of each run, choose 1 weapon from 2 random options. During the run, level up and choose 1 upgrade from 2 random choices. You can strengthen your main weapon, or lock in one secondary weapon to cover your weakness. Once selected, the secondary weapon cannot be changed until the next run. Each weapon has its own identity. Some weapons are better at damage, some are better at control, some are better against swarms, and some are better against bosses. There is no single best weapon. A good build matters. Survive 10 waves, face 3 boss fights, and protect your base HP. Boss death does not automatically clear the wave — you still need to defeat the remaining enemies. Features: - Auto-firing defense gameplay - No manual aiming or movement - 2 random starting weapon choices - 2 random upgrade choices on level-up - 1 main weapon and 1 locked secondary weapon - Weapon-specific upgrade paths - Randomized enemy waves - 3 boss fights in 10 waves - Daily and lifetime leaderboard competition - Short runs designed for mobile play Build better. Survive longer. Rank higher.
