ERZ Online is a multiplayer sci-fi sandbox where you control a mining robot and carve your way through procedurally generated underground worlds. Dig through layers of alien rock, extract valuable resources, and explore the unknown.

Unexplored areas are hidden in darkness — the only way forward is to physically break through and create your own path. In dangerous zones, the loot goes into your cargo, and you must bring it back safely to secure your progress.

Core Gameplay Loop

You start with a simple robot and a direction.

Move into the rock → open a path → discover resources → extract them → carry them back → unload → upgrade your bot → go further.

Every decision matters: where to dig, how far to push, and when to turn back.

What Makes ERZ Different

Explore the unknown
Large parts of the world are hidden in darkness. Progress is not given — you uncover it yourself, tile by tile.

Risk vs reward mining
In dangerous areas, resources are not secured instantly. You must transport them back, balancing greed and survival.

Physical path building
There are no pre-made routes. Every tunnel is created by players, shaping the underground world.

Procedural underground worlds
Each session offers new structures, resource layouts, and opportunities.

Multiplayer environment
You exist in a shared world with other players, where routes, discoveries, and activity shape the overall experience.
