There is no actual player limit, but the recommended team size is 4. Use the proximity voice chat to communicate with friends and play with many sound altering artefacts.
Explore with friends the depths of liminal bunkers and take any artefact that you come across.
Identify forgotten artefacts to deduce their effects on you or on your friends. Draw descriptive pictures to not forget what they do or sacrifice them to go deeper into the bunkers.
While delving deeper and deeper into the bunkers, rooms will get more dangerous, traps that keep scavenger at bay will be more frequent and artefacts will be more and more lethal.
