Wall World is a mining rogue-lite with tower defense elements set on the enormous surface of a mysterious Wall. You explore procedurally generated mines, discover fantastical biomes, and gather resources and technologies to buy valuable upgrades, all while fending off hordes of aggressive monsters using your mobile base. You can roam the Wall freely by day and night and in varying weather, following traces of others and mining where no one has mined before.
The loop weaves together several activities. You burrow deep into the Wall at different points in search of resources and technologies and to uncover new biomes, but must always return to your robospider in time for the next monster attack. When the creatures come, you shoot and hack at them with weapons ranging from simple machine guns to homing missiles, and you can break camp instantly to continue fighting on the move.
Upgrading and building deepen your survival odds. You modernize your exosuit to move faster and break through tougher rock, boost your robospider's combat stats, and construct automatic turrets, repair stations and resource harvesters, though blueprints must first be found in the depths. Blending action, adventure, indie and strategy on PC, it rewards exploration of its strange, biome-rich Wall.
