In the gripping cooperative horror world of *R.E.P.O.*, you'll encounter a variety of mischievous and dangerous creatures that make every mission a tense and unpredictable challenge. As you explore abandoned locations in search of valuables, you must be prepared to face terrifying monsters that are determined to halt your progress to the next level.
Each monster in *R.E.P.O.* comes with its own unique set of abilities, behaviors, and attacks, demanding that you adapt your strategies to ensure your team's safe return to the truck. Some monsters are stealthy, stalking you in silence before they strike, while others are more boisterous, making it impossible to hide. Yet, even these loud monsters pose a threat, as some are attracted to sound, pushing players to move quietly. Conversely, others rely solely on sight, making it crucial to keep them in your line of sight to survive.
With such a diverse array of monsters, it's essential to distinguish between those that are merely a nuisance and those that pose a significant threat. Knowledge is key in survival games like *R.E.P.O.*—understanding each monster's behavior and damage potential can significantly improve your chances of survival.

Gnomes | 1 | They inflict minimal damage and are easy to eliminate. |
Animal | 1 | Individually, they cause little harm and can be picked up easily. They can also destroy Gnomes they encounter. |
Hidden | 1 | Can transport you back to the truck or into a monster's path, but doesn't cause direct damage. |
Shadow Child | 1 | Remains harmless as long as you avoid looking at it. |
Spewer | 1 | Once attached, it can be utilized against other monsters without harming you. |

Peeper | 2 | Inflicts minor damage when eye contact is made, but can become troublesome if other monsters are nearby. |

Bangers | 2 | You have a 10-second window to escape once their dynamite ignites—dangerous only if caught in the blast. |
Huntsman | 3 | Tracks players by sound—silence is your ally (and the duck can't betray your position). A gunshot could end your game. |

Clown | 4 | Charges upon sighting you with two lethal attacks: a kick and a laser. |
Robe | 4 | Silent and often sees you first. Can maneuver under furniture to reach you and is deadly once it catches up. |
