Basically,,, ahem ahem,,

The Pandemonium World is the ever-changing main location of PP. it was created by Ultra M, the main antagonist, where he kidnaps people from across the multiverse to take part in his twisted “murder game show” to see who can get the most kills,,, over the span of 1000 YEARS.

The rounds aren’t necessarily canon. Those are just a certain killer happening to stumble upon a group of survivors and picking them off.

The pandemonium world is split up into different sections, with a new one being created every time a killer enters by accident. The main area is the survivors’ hideout, where they hide from the killers. However, they gotta go out and get supplies every now and then, and quite often they will encounter one of those killers.

There IS internet, with a website containing data about every killer, poorly managed by every survivor.

sometimes, ultra M himself decides to join in on the fun, and comes down as a killer himself!!

Ok that’s all the lore explodes
