Casualties Unknown enemies and traps

Short answer: most Casualties Unknown enemies chase, bite and retreat, so keep a wall between you and them and punch when they come in. Traps cause more deaths: most can be broken safely by digging under them or throwing a junk item at them, and turrets, landmines and sound cannons need the most respect. confirmed

Everything below was observed on Demo 7.0.1, the last public build before release. The developer says traps are “more clearly telegraphed” and combat is “less finicky” in the full game. confirmed

What enemies are in Casualties Unknown?

Enemy Layer Danger How to handle it
Shade crawler 1 onward Low Mills about; punch until it dies. Bleeding and venom are minor
Cave ticks 2 Swarm Stay still until you pass. If triggered, run and put a wall between you
Sand stalker 3 Low Chases and retreats after each bite; a wall stops it reaching you
Wall biter 3 onward High early Avoid in a one-on-one until you have a weapon
Overgrown tick 5 Low Same pattern as other enemies
Young thornback 5 Moderate to high Common in layer 5
Elder thornback 5 Boss You get a warning moodle. Prepare or leave

The enemy guide notes that nearly all enemies behave the same way, so one approach works for most: wait for them to come to you, and hit them as they arrive. confirmed Cave tick venom was cut by 75% in 7.0. confirmed

What is the sense of impending doom?

A moodle that warns you an elder thornback is on its way. Players nickname this boss “the salad”. confirmed Its side effects are a real problem on their own: forum players say the moodle spikes adrenaline, driving up blood pressure, and if it lasts too long it can lead to a stroke. reported Treat the warning as a signal to act immediately.

What traps should you watch for on each layer?

Trap Layer Danger Safe way to remove it
Jump pad 1 Low to moderate Punch it or break the ground under it
Spike trap 1 Very high if it hits you Throw a junk item above it; the item is destroyed
Geyser 1 Low Move away; moving liquid pushes you around
Glass shards 1 Low Break them instead of walking on them
Bear trap 2 Low to moderate Destroy it the same way; it holds you in place
Barbed fence 2 Moderate Break with claws, or remove the blocks below
Landmine 3 High Throw an item from far away
Turret 3 High Bait a shot, then punch it and run
Coil 3 Moderate to high Needs a tool, and hitting it by accident is easy
Stalactite 3 Low alone Break it by hand
Toxirock, spent fuel 4 Low Keep distance; barrels are nearly indestructible
Sound cannon 4 Moderate Get behind solid cover within 5 seconds
Skullcrusher 5 Higher than stalactites Same approach, bigger hit
Grabber plant 5 High Avoid the tip

All of these are from a full walkthrough of every hazard. confirmed

How do you survive a sound cannon?

A sound cannon wakes when you get within a screen of it. If it has a direct line of sight, it locks on and charges for about five seconds. Put a solid wall between you and it during that time. confirmed A hit causes pain, hearing loss, internal bleeding and brain damage, and being submerged with it makes the damage far worse. confirmed

They fire once, after which you can break them safely. confirmed The 6.0 patch made them less loud and added a mute effect on the game’s volume instead, so a sudden silence is a sign of a hit. confirmed

Which traps ragdoll you without touching them?

Bounce pads, barbed wire and coils can knock you down when you go very close, without actually hitting you, as one video test shows. confirmed The visible trap looks smaller than the area that affects you. Landmines, sound cannons and turrets must actually hit you. confirmed This matters on ledges, where a ragdoll sends you into something worse.

How do you turn traps into materials?

Destroyed traps are a good source of metal and circuit boards. confirmed Digging out the block beneath a trap usually disables it at once, while hitting it directly takes longer and risks setting it off. Turrets drop plenty of scrap and a circuit board, but explode shortly after you damage them enough, so leave quickly. confirmed Those materials feed into crafting and trade well.

What do Casualties Unknown beginners get wrong?

  • Walking under stalactites while climbing. They drop whenever you pass beneath.
  • Standing in front of a turret’s line. It only shoots horizontally, so stay off that line.
  • Pulling shrapnel straight away. Pain makes your hands shake. Bandage first, then pull it out.
  • Trusting a bush in the desert. Mines hide inside them.

Enemies may also appear in new forms below layer 5 in the full game, and we will add confirmed ones after recordings appear.
