Summary

The Floating Head is one of the hardest monsters to run away from as it’s incredibly persistent once it notices you. Its attacking phase is evident by its widened eyes and open mouth, where it will lunge and bite you if it gets close.

It also can become aggressive when a light source (flashlight) is shined onto it if it is looking towards the direction of the source, even if the unaware player is in the next room.

Behavior

The Headman is a giant head that will float around looking for players, making distinct biting noises.

It is extremely sensitive to flashlights, but otherwise is only enraged if you're not hiding and close to it. If you look at it with your flashlight on regardless of distance, it will charge the player while hissing and attempts to chomp them, dealing 50 damage per bite, plus some possible physics damage from the knock back.

Survival Tips

Stay behind the Floating Head whenever you can.
Use furniture to hide from it.
Never run away in a straight line.
If spotted, run to a corridor that has an alcove or a side room, shutting the door behind you. While it can open doors, it will lose track of you if you’re quick enough.
As long as you don't put your flashlight on it or damage it, it shouldn't get enraged.
Turning a corner and immediately hiding seems to be effective in losing it if it's chasing you.
If you're a maniac like me and want to fight it, wait for it to use its attack. It has a long cooldown and its movement is very erratic. It's also worth mentioning that one of its bigger weaknesses is its poor reach.
Therefor, I recommend the sledgehammer, as it won't be able to bite you back if you keep swinging that thing, and they have surprisingly low hp.
Guns are very effective against it as well, since it has a massive hit box to compensate for their inaccuracy.
