Backpack Raiders

Backpack Raiders is a survival game about a mercenary raiding cities overrun by mutated bugs. Decades after a catastrophe wiped out humanity, the bugs rose from the ruins and made entire cities their hives. You breach the infested city walls to collect valuable bug parts and earn a profit in the new world.

Fight the swarms

You dash, shoot, blast or slice through escalating swarms in quick waves, then try to survive long enough to extract. Combat combines auto-firing with manual aiming. Runs are designed to be quick and chaotic, with hundreds of items and many possible synergies.

Build your loadout

Your backpack is a grid-based inventory where you arrange weapons, trinkets, attachments and oddities. Each item's shape and effect contributes to your build, and its position, adjacency and orientation matter. You can discover items with unique shapes and effects, create synergies through placement, and merge items into new, powerful tools.

Develop your outpost

Raids earn supplies that you spend between runs to construct buildings and gain permanent upgrades that boost future runs. Place workshops, armories, trading posts and other specialty structures to gain bonuses, unlocks and stronger starting loadouts. Strategic placement can create synergies between buildings.

Construct specialized housing and facilities to unlock new mercenaries and loadouts. Some buildings let you set the difficulty, with better rewards available at higher settings.
