Redface

Description
Redface is a glowing red light, it flies through walls moves faster than a sprinting human and instantly kills the player upon contact, jumpscaring them. Redface spawns as a consequence for not refueling the generator, spawning 3 to 5 minutes after the generator runs out of power.

Once Redface spawns, all ambient sounds will cut out, and a loud rumbling can be heard as Redface approaches. Redface will kill the player roughly 15 seconds after spawning, one at a time and there is no way to avoid it once it spawns besides having already Escaped on the elevator. Redface can be prevented from spawning by fuelling the generator. The generator starts with 1 minute of power (Displayed as 1:00 on its clock), and can be refueled with fuel canisters found around the map. Refueling the generator sets the timer to 5 minutes, no matter how much time is left on the generator.

When the generator runs out of power, a loud bellow can occasionally be heard. Eventually, there will be four loud bellows in a row, which serves as the final warning. After the fourth bellow, Redface will spawn, and the generator will lock. Attempting to fuel it will give the message "The generator won't start."

Tips

 * Keep the generator refueled. If you don't, Redface will eventually spawn, leading to an inevitable death.
 * Once all ambience cuts off and loud rumbling can be heard, you are guaranteed dead unless you have Escaped.
 * Unlike the other monsters, Redface isn't a huge threat. It makes refueling the generator crucial but will pretty much only appear once per game while the others appear constantly. This does NOT mean that Redface should be taken lightly and disregarded as a meager threat.

Trivia

 * Like the other monsters, it appears as a poorly drawn face. One thing that is unique is that it's red, earning its name, Redface.
 * Using exploits, you can see that Redface's official name is Shadow.
 * It will still chase players even if they are escaping on the elevator, jumpscaring them without killing them.
 * Redface has a unique jumpscare. If the jumpscare of the other monsters is just a picture that sticks to the screen, then the redface jumpscare attracts the player's camera to his face.
