Stack Tower 1.3 — boss fights, a second cannon, and a stocked store

We said a bigger combat update was in the works — here it is. Version 1.3 turns the fight above floor 50 into a proper campaign, with bosses to hunt, a new prestige upgrade to chase, and a fresh coat of audio polish on everything.

Boss enemies

Every tenth enemy is now a boss: twice the size, ten times the health, a faster gun, and a wild spray of shots instead of aimed fire. Taking one down scores extra — and starts you on a new line of achievements: Giant Slayer, Boss Hunter, and Titan Breaker bring the total to 39.

Mount a second cannon

A new prestige upgrade lets you fit your ship with a second cannon and fire in pairs. It's a serious commitment — and a seriously wider shot pattern for the deep floors where bosses stack up.

A store worth browsing

The store has been reorganized into clean, browsable sections: avatars, profile frames, ten aircraft skins, backgrounds, and tower tiles. Everything is unlockable with coins you earn by playing.

Hear every hit

New sound effects land with every shot, hit, explosion, perfect drop, and power-up pickup — and bosses announce themselves with a sound of their own.
