Casualties: Unknown Guide: Essential Crafting, Movement, and Survival Tips

Master crafting, intelligence leveling, medical triage, movement tech, and layer survival with this comprehensive Casualties: Unknown guide.

Descending as an XB into the subterranean layers of Casualties: Unknown means every mistimed jump, untreated infection, or wasted battery can abruptly end a run. Because the game buries critical systems under unforgiving physics and intricate medical mechanics, having a reliable Casualties: Unknown guide turns chaotic trial-and-error into repeatable progression. Whether you are starting your first Normal run after completing Basic Training or pushing toward Layer 5, this Casualties: Unknown guide covers the essential crafting recipes, triage habits, movement tricks, and enemy strategies you need to survive.

Mastering Early Inventory, Crafting, and Intelligence Leveling

On the title screen, selecting "Descend" lets you choose between Relaxed, Paradise, and Normal difficulties. Normal is the standard baseline once you finish the built-in Basic Training tutorial. From the moment you land, your survival depends on gathering gear efficiently and leveling your Intelligence, which starts at 7.

You do not need to hold ingredients in your hands or even carry them in a bag to craft. Simply drop required materials onto the floor around your character and assemble the item directly from the menu. Holding Control displays floating labels over nearby ground items, and clicking a consumable on the ground through the center of your inventory uses it immediately without picking it up.

Community reports highlight several inventory habits that prevent costly mistakes early in a run:

  • Toggle mouth-held flashlights cleanly: Dragging an item to the center of your inventory activates it. Keep a flashlight in your mouth when both hands hold tools or large containers—it still aims toward your cursor, and you can toggle it from your inventory window.
  • Protect essential tools: Crafting consumes loose materials and tools on your person before pulling from bags. Favorite sticks and key gear so recipes do not accidentally eat your digging implement.
  • Salvage 1% durability gear: Upgrade recipes usually accept nearly broken tools. You can wear a machete down to 1% durability while digging before upgrading it into a titanium version.
  • Consolidate scrap and batteries: Drag scrap pieces onto each other to combine them into lower-weight cubes, and use a wrench on lightbulbs or spare PDAs to harvest and swap batteries. Selling battery-powered devices like extra auto-pumps yields full credits (around 20 credits) if you swap in a fully charged small battery first.

Intelligence XP and Crafting Risks

Attempting a recipe above your current Intelligence introduces crafting penalties. Being one level short triggers a minor risk, meaning the craft always succeeds, but items with durability—like tools or armor—may spawn slightly or heavily damaged. Being two levels short creates a major risk, where the craft can fail completely and destroy your materials.

To level Intelligence safely, read every blueprint and powered PDA you find, haggle with every trader except Dune (who will eat you), and craft simple items for the first time to claim the 10 XP discovery bonus. According to the official Casualties: Unknown Wiki, easy training crafts include turning four foliage into wood scraps, turning wood cubes into wood panels, hammering ceiling hangings into rflowers, processing shade crawler blood sacks into alien blood, and combining stone fruit with a stick and chem fuel for flammable powder.

16–18Tactical Boots, Mini Laser Drill, Riot Helmet, Neural BoosterUse only one neural booster; note that helmets do not grant full immunity to stalactites.

For liquids, player experience strongly favors carrying four IV bags inside containers rather than using a liquid pouch, which weighs significantly more. You can mix crafting fluids in a single bottle without ruining them, though newly crafted liquids must be poured in manually. Because IV bags cannot scoop water directly from floor tiles, keep a milk carton or chocolate milk bottle handy for collecting groundwater.

Medical Triage, Sleep Safety, and Temperature Control

Understanding health stabilization separates veteran XBs from early casualties in any Casualties: Unknown guide. Rather than panicking over every status icon, learn which threats demand immediate action and which ones can wait.

Bleeding, Pain, and Infection Rules

When suffering multiple bleeds, alternate dressings across wounds until you see the bandaged icon or a small white droplet. Prioritize wounds showing a yellow blood icon, as these drain your blood supply rapidly, whereas minor non-yellow bleeds can occasionally wait if your blood reserves are stable. Avoid using glowfruit to disinfect wounds whenever possible; player experience confirms it damages local skin health—tracked by the shield icon in the bottom-left—which ironically raises your odds of developing an infection.

Managing painkillers also requires precision. Based on community reports, loading 2 mL of fentanyl into a syringe by itself provides safe pain relief, provided you avoid stacking additional doses afterward. For brain damage, braingrow from crates or traders is the primary reliable cure, since natural recovery happens extremely slowly.

Food, Sleep, and Climate Survival

Sickness is far less lethal than it appears. As long as your nausea moodle stays at "queasy" (roughly 25%), eating unappetizing animal corpses remains a safe way to prevent starvation. Balance your mood and weight across layers: geofruit in Layers 1 and 2 boosts happiness (just stop eating once the "slaked" overhydration moodle appears), while blobflesh restores weight. In Layers 3 and 4, forage cactus flesh, brownshrooms, popfruit, and stone fruit to brew produce juice.

Status / HazardPrimary CounterplayCritical Mistake to Avoid
Low Energy (<35%)Sleep on rubber or sand; eat naptails or sleeping pills; drink coffee/soda for temporary bursts.Sleeping with low skin health (causes wound infections) or open bleeds without blood reserves.
Severe Cold (Ice Layer)Use the workout button (bottom-right of health menu) to generate heat and keep moving while stamina regens.Standing idle after exercising, which lets body temperature plummet again.
Overheating (Desert)Remove insulated gear (scarves, limb wraps), jump into water or oil, and sip water or juice.Keeping high-insulation armor equipped while sprinting through hot biomes.
Multiple BleedsAlternate dressings across wounds; address yellow blood icons first.Over-wrapping minor white-droplet wounds while a major bleed drains you.

Before sleeping to heal muscle damage and injuries, exercise to burn off remaining energy and double-check that your wounds are disinfected and wrapped. In desert biomes packed with foliage, late-game players can spam-craft scarves and pack them into a material pouch—each scarf weighs the same as a single piece of canvas, tears into emergency bandages, and sells well to traders.

Advanced Movement Tech and Darkness Navigation

Standard walking and jumping will not carry you across every chasm or out of tight traps. Learning a few physics-based movement techniques is a core pillar of any effective Casualties: Unknown guide, especially when your light source dies or you play unchipped.

  • Throw-boosting: Jumping a split second before throwing a heavy item—such as a mini-barrel—propels you in the opposite direction. Aim downward for extra vertical height or backward to clear wide horizontal gaps.
  • Ragdoll wiggling: Holding X drops your XB into a ragdoll state, letting you scoot through two-block gaps to conserve digging stamina or slip inside metal loot containers with glass windows. Always exit ragdoll mode before digging to avoid injuring your hands, and remember you cannot stand back up until your momentum stops.
  • Punch boosting: Striking the ground on the exact frame you jump grants extra burst mobility at a steep stamina cost. You can also chain this off wall jumps by angling your punch downward.
  • Climbing and dark scanning: Keep one 100% durability scrap metal piece on hand to place emergency foothold blocks (consuming 25% durability per block). If darkness, a solar flare, or an unchipped run blinds you, sweep your cursor across the screen to highlight and label drop-offs, and toss glowplant fruits ahead of jumps to reveal hidden hazards.

Disarming Traps, Farming Loot, and Defeating Layer Threats

Beneath the upper layers, environmental hazards and aggressive creatures test everything covered in this Casualties: Unknown guide. Assume every pile of foliage, corpse, and puddle conceals a landmine until proven otherwise.

You can safely bait jump pads, spike traps, and sound cannons by tossing spare items into their triggers or stepping briefly into line of sight before dashing back into cover. Most traps can be neutralized by mining the tiles directly beneath them. Avoid landmines, electrical coils, spent fuel, and flowing water—always destroy nearby geysers before looting a flooded room.

Salvaging Drill Pods, Turrets, and Locked Rooms

Resourceful players turn dangerous machinery into high-tier crafting supplies. Breaking drill pods with a digging tool while speeding up time yields plentiful 100% scrap and circuits. Turrets drop the same valuable components if you bait their initial shot, rush in to punch them until they begin beeping, and sprint clear before they detonate.

If you encounter locked vaults requiring red blood to open, dynamite crafted from cheap blast powder offers an alternative entry method. Position the charge far enough from the interior crates so the blast breaks the wall without destroying your loot—and clear the blast radius immediately.

Handling Shade Crawlers, Cave Ticks, and Salad

Not every enemy deserves a fight. Hunt shade crawlers early until you secure two stiff carcasses for a makeshift helmet, and remember that throwing random objects deals damage and briefly stuns creatures. Conversely, cave ticks drop zero loot; seal tunnels behind you with placed blocks rather than wasting health or durability on swarms.

ThreatLoot / RewardRecommended Strategy
Shade CrawlerStiff carcass, blood sack (alien blood XP)Fight early for helmet materials; stun with thrown items.
Cave TicksNoneAvoid entirely and wall off tunnels to block pursuit.
Turrets & Drill Pods100% Scrap Metal, Circuit BoardsBait turret shot, punch until beeping, flee; dig drill pods while speeding time.
Salad (Layer 5)Progression / survivalBack-strafe its 3-second lunges; finish Phase 2 fast with firearms or dynamite.

Salad in Layer 5 requires careful spacing rather than blind panic. In its initial hunting phase, Salad moves toward your position roughly every three seconds, allowing you to back-strafe safely as long as you avoid dead-end corners. If it lands a bite during this first phase, it goes dormant for roughly five minutes. Once it enters its enraged second phase, however, its movement intervals accelerate and a bite removes the dormancy grace period—meaning it will relentlessly pursue you until death. Player experience recommends avoiding pure melee fights here and relying on firearms or well-timed dynamite blasts to finish it quickly.

Frequently Asked Questions

How does crafting risk work in this Casualties: Unknown guide?

Crafting one Intelligence level below a recipe's requirement creates a minor risk: you always receive the item, but tools or armor may spawn damaged. Crafting two levels below creates a major risk, giving the recipe a chance to fail completely and waste your ingredients.

What is the fastest way to raise Intelligence early on?

Read every blueprint and battery-powered PDA you discover, haggle with traders (excluding Dune), and craft simple materials for the first time to collect 10 XP per new recipe. Easy early crafts include wood scraps from foliage, wood panels from wood cubes, and rflowers from ceiling hangings.

How can I survive extreme cold or desert heat without specialized gear?

In freezing zones, open the bottom-right of your health menu to work out and generate body heat, keeping your character moving while stamina recovers. In the desert, strip off insulated scarves or limb wraps, submerge yourself in water or oil, and drink produced juices to lower your temperature.

How do I beat Salad in Layer 5 without getting cornered?

Keep open escape routes behind you and back-strafe every three seconds whenever Salad lunges toward your previous spot. Save firearms or dynamite for its faster second phase, since getting bitten late in the fight prevents it from going dormant and forces a fight to the finish.
