Short answer: Yes, you can kill monsters in R.E.P.O. Long answer: Some are weak, some are tough, and some will just laugh at your attempts. Below is a breakdown of which entities can be killed, how much money you get, and the best way to take them down.Monsters and How to Kill ThemAnimalWeakness: Anything. Just smack it.Tips: These things run like headless chickens but have no real attack. They die in 1-2 melee hits. They also trample Gnomes, so keeping them alive can be useful.BangerWeakness: Throw them or let them explode.Tips: You can pick them up and toss them like grenades, but be careful—if their fuse is lit, they will break free after a few seconds. The best way to kill them is to toss them into water, lava, or acid.GnomeWeakness: Gravity.Tips: Pick them up and slam them into the floor. Works every time. They die instantly. You can also throw them at other entities for some damage.PeeperWeakness: Looking away.Tips: You can’t kill it, but you can avoid taking damage by breaking line of sight ASAP. If it catches you, move behind a table or into another room.SpewerWeakness: Any melee weapon.Tips: If you don’t want to kill it, just pick it up and shake it. Otherwise, it dies fast if hit with a melee weapon. Be careful—it vomits on death, and that can damage scrap.Shadow ChildWeakness: Any melee weapon.Tips: They teleport and jumpscare you, but they have hilariously low HP. One good smack with a melee weapon should do the trick.RugratWeakness: Slamming it into the floor.Tips: These things steal and throw valuable items at you. If you can lift one (requires 2-3 people or strength upgrades), smash it into the ground or a wall to kill it.BowtieWeakness: Guns or melee.Tips: When it’s screaming, it’s an easy target for a tranq gun or a melee weapon. It has very low HP and dies in 1-2 melee hits.Apex Predator (Duck)Weakness: Getting crushed.Tips: Attacking it just makes it go berserk. The easiest way to kill it is to trick it into standing in an extraction point and let the machine do the work.MentalistWeakness: Melee weapons, but it's tricky.Tips: They float and use anti-gravity to mess with you. If one is close, hit it with a melee weapon before it traps you. They have low HP but can teleport, so keep an eye out.Chef (Tumbler)Weakness: Dodge and counterattack.Tips: It jumps at you, so be ready to move. If it misses, it gets stunned for a few seconds—use that time to hit it hard.ReaperWeakness: Melee weapons or tranq guns.Tips: They’re blind but have long reach. If they see you, don’t hide right away—run, turn a corner, then crouch. If fighting, use melee weapons but be careful—they can knock items out of your hands.HeadmanWeakness: Sledgehammer or guns.Tips: Do NOT shine a flashlight at it. If you want to fight, bait out its bite attack and counter with a melee weapon. It has a big hitbox, so guns are also great.HuntsmanWeakness: Grenades, land mines, or other enemies.Tips: He has a shotgun and will kill you instantly if you’re close. If you must fight, bait out a shot, then attack while he reloads. He’s blind, so use distractions.Clown (Beamer)Weakness: Cover, crouching, and patience.Tips: When it laughs, it’s about to fire its laser. Hide behind indestructible cover or crouch under it after it starts. It has a long cooldown after attacking—use that time to hit it.RobeWeakness: Avoidance.Tips: Do NOT look at its face. If you do, it will sprint at you. If you must fight, use explosives. It has very high HP.Trudge (SlowWalker)Weakness: Land mines, but not worth it.Tips: It’s the slowest enemy but has a massive pull attack. If you see it, leave. If you must fight, explosives are your only real option.UpscreamWeakness: Tranq gun or melee.Tips: If alone, it’s no problem. If there are two or more, they will stunlock you into oblivion. Use a tranq gun or melee to take them out quickly.Monsters That Are Basically ImmortalThese guys can’t be killed (or at least, nobody has figured out how).Peeper – Just break line of sight.Hidden – No one really knows what’s going on with this one.Trudge – Has absurd HP and isn’t worth fighting.Clown – Can technically die, but it’s not practical.Huntsman – Can be killed, but not worth the risk.Final BlurbIf an entity drops money, kill it.If it has a shotgun or laser, run.If it’s slow but tanky, just leave it alone.If it’s a Gnome, smash it into the ground immediately.Some enemies are worth the fight, but others are just a waste of time (or your life). Plan accordingly, and remember—sometimes running is the best strategy.
