The first thing to know is that the mode is divided between two teams: Props and Hunters.
Being a Prop is as exactly as it sounds: You play as a random object specifically designed to fit into the surroundings of whichever map you’re spawned into. Although being a Prop is far better than being one of your inanimate peers, you can be destroyed if a Hunter finds and damages you, and every 30 seconds, you have the uncontrollable urge to whistle.
However, since a Prop could fit into its surroundings, you should be able to find a nice inconspicuous spot to hide.
As a Prop, you’ll get a short period of time to find your hiding spot before the Hunters are released. Every 30 seconds, all surviving Props make a loud whistle noise that helps Hunters figure out where they are.
Other than finding a phenomenal hiding space and waiting out the clock, Props have a few other tools at their disposal to fight back Hunters. These are:
Decoys: These are carbon copies of whichever Prop you happen to be. Place your decoys in areas that will throw off Hunters while you’re tucked away somewhere they can’t find. There’s an art to doing this and it’ll take some time to master, but with enough practice, you’ll be able to use decoys to effectively throw Hunters off your trail.
Changing Shape: If you don’t like your current Prop, or if you’ve been spotted and you need to make a quick getaway, you have the option to switch to another one. You can only do this a limited number of times, so make your switches count, and make do with whatever shape you end up with… Even if it is as ridiculous as a baby grand piano.
Stun: If a Hunter gets too close for comfort, Props have the ability to stun them with a Flashbang-like explosion. Doing this will give you a few seconds to make a quick getaway.
