So, i've been walking for more than one hour now. I contacted two survivors, i really hope i can trust them. Level 265, through noclipping... But then i noticed something. There is a hole in the ground, there stands, "Exit". This is probably just a way to Level Fun =), i think. I forgot the others meanwhile.
The floors get darker, what is happening? This looks like...Level 1! I did it! At least there is water on the ground! *tastes the water* Eh, that tastes dusty. Maybe i can find a base with real water, so lets continue the exploring!
