What it would be like in Worldwalk imagined

Nobody has seen the surface of K2-211 b. The game builds it from the real numbers above: you land on a molten surface of lava seas.

Pack the right suit. Choose 3 of 6 modules (cooling, heating, pressure hull, extra oxygen, radiation shield, jetpack), complete 3 surveys and get back to the lander before your oxygen runs out.
