Start designing and building NOW!


The idea for {Undefined} came, because conventional games provide you with premade building blocks which can then be used to build stuff. But premade blocks always bring limitations. So we created {Undefined} where we provide as little premade objects as possible!

{Undefined} is a sandbox survival game like no other, set on life-sized voxel planets with realistic phyisics with the possibility to shape your own building blocks. From your custom made furniture, walls, crafting stations to vehicle parts. You shape the blocks which can then be used to build buildings, spacecraft and aircraft. Endless possibilites with as little limitations as possible!

Survive, gather resources and start designing and building!
