The world has fallen. A zombie horde is closing in, and your backpack inventory is your last strategy board.

Backpack Defense: Zombie TD is a grid-based backpack / inventory management game that blends merge upgrades with roguelike tower defense. Pack smart: arrange weapons in your grid and slots to deploy them on the Defense Line—each weapon summons an Eidolon to fight the zombie waves.

Merge, combine, and upgrade weapons to grow stronger. Reach Lv.3 to unlock two branching upgrade paths and shape a build that fits your playstyle. Defeat zombies to gain EXP, level up mid-run, and draft Battle Cards to create fresh strategies every run.
