Explore the mysterious Wall World on your giant robospider: mine for valuable resources, upgrade your equipment to fight off hordes of monsters, and discover exotic biomes in-between attacks. Will you be able to survive and learn the secrets of the Wall World?
At the core of the gameplay, you control a robotic spider mech that can scale the seemingly endless vertical Wall. By drilling into weak spots, you access procedurally-generated caves and mines. Once inside, you disembark from the mech and use a plasma cutter tool to harvest resources like ores and minerals.
The mining process is timed, as you must return to the spider mech within a set limit before waves of hostile alien creatures, known as Zyrex, attack. This creates an engaging loop of quickly exploring the mines, gathering as many resources as possible, and then defending the mech from the oncoming onslaught.
The resources you gather can purchase permanent upgrades for the spider mech between runs, providing a strong sense of progression. As you become more powerful, you can venture deeper into the Wall, accessing new areas and discovering more secrets.
To aid in the defense, you can construct automated turrets, repair stations, and resource harvesters within the mech's vicinity. Managing these defensive structures and timing their deployments is crucial to surviving the increasingly difficult Zyrex waves.
The game's procedurally-generated caves and biomes, combined with the variety of upgrades and tools, allow for emergent gameplay experiences. You can experiment with different loadouts and tactics, discovering synergies and strategies that help you progress further. This unpredictability and adaptability maintain the game's replayability, as no two runs feel exactly the same.
