A possible concise summary is:
Four friends play a game of Prop Hunt, where they have to hide and seek as different objects in a horror hotel map. They make jokes about "coming-coming-going-going", which is their term for ejaculation, and try to find each other using clues and glitches. They also encounter zombies, head crabs, and a creepy baby. They laugh a lot and scream a lot, and sometimes kill each other with bombs. The video ends with a clip of one of them hitting another with a bottle repeatedly.
