Backpack Idle

Backpack Auto is an idle tower defense game where your build matters just as much as your upgrades.

Collect hundreds of randomized items, arrange them in your backpack, and discover powerful combinations. Weapons trigger other items, which can trigger even more effects, creating massive chains of attacks, missiles, explosions, and elemental reactions.

Defend your tower against endless waves of enemies, upgrade your equipment, and push through increasingly difficult tiers.

Your tower keeps fighting while you're away, earning gold and loot even when the game is closed. Come back, improve your build, and see how much farther you can get.

Features:

• Hundreds of items with unique effects and synergies
• Recursive proc chains and backpack-based buildcrafting
• Endless waves, bosses, and increasing difficulty tiers
• Equipment upgrades, crafting, and randomized loot
• Offline progression with automatic farming
• Experiment with Fire, Poison, Freeze, missiles, and more

Build it. Break it. Make it better.
