Backpack Defense War

Backpack Defense War redefines classic tower defense gameplay with a unique inventory management core. Before each battle round, you can spend coins to purchase and refresh various offensive and defensive units and weapons, which only activate combat effects when placed adjacently in your backpack grid. Identical items can be merged to level up for stronger attack power and better survival capability. Defeating enemy swarms earns you extra gold to unlock more backpack slots and build exclusive combat formations. As stages progress, enemies grow tougher and more numerous, forcing you to carefully balance space layout, damage output and defense sustainability to create different build strategies. Featuring roguelike randomness, thoughtful tactical depth, simple controls and fast-paced casual rounds, this game delivers relaxing yet challenging fun perfect for short play sessions anytime and anywhere.
