Gunsaw — Casualties: Unknown Wiki

The Gunsaw is the defining signature hybrid tool and melee weapon in Casualties: Unknown (originally created by Orsoniks as the namesake asset in his preceding title, Gunsaw). Combining a high-torque internal combustion engine with a rotating, tungsten-reinforced diamond blade chain, the Gunsaw serves a dual role: it obliterates reinforced rock walls faster than any pickaxe, while simultaneously eviscerating charging subterranean predators.

How to Obtain the Gunsaw

Method 1: Industrial Scavenge (Layer 4+)

The Gunsaw occasionally spawns in pre-war military crates and maintenance lockers located in:

The Fungal Basin (Layer 4): Inside flooded industrial pump stations (~2.5% spawn rate).
The Industrial Sump & Rail Depots (Layer 5): Secured inside locked steel lockers requiring a lockpick or cutting torch (~8.0% spawn rate).

Method 2: Crafting at a Machining Bench

If you cannot find a pristine Gunsaw in the wild, you can fabricate one from raw materials once you have unlocked the Machining Bench:

[Crafting Recipe: Gunsaw]
├── 4x Titanium Alloy Ingot    (Smelted from Titanium Ore + Flux)
├── 1x Rotary Blade Assembly   (Machined using Diamond Grit + Steel Scrap)
├── 1x Motorized Engine Core   (Scavenged from broken generator pods)
├── 2x Industrial Rubber Belt  (Crafted from raw resin or synthetic rubber)
└── 2x Heavy Machine Oil       (Refined from black cave oil deposits)

Combat Mechanics & Tactical Usage

1. Shredding Apex Predators

Against high-health beasts like the Elder Thornback, the Gunsaw is one of the few weapons capable of breaking through reinforced chitin armor. Continuous revving applies stacking bleed ticks, causing enemies to lose blood rapidly even after they disengage.

2. Rapid Emergency Tunneling

When trapped by rising water levels, falling rockslides, or toxic gas leaks, revving the Gunsaw into ceiling tiles or stone walls opens a 2x1 escape crawlway within 3 seconds, bypassing normal digging delays.

3. Noise & Aggro Management

The greatest danger of the Gunsaw is its engine volume. Running the blade draws all hostiles within a 35-tile radius. Always clear immediate rooms before using the Gunsaw for mining, or prepare defensive barricades before firing up the motor.

Maintenance, Blade Sharpening & Repair

Operating a dull Gunsaw increases motor stall rates and halves combat damage. Maintain your weapon with these steps:

Field Sharpening: Use a Whetstone or Diamond File to restore edge sharpness. Restores 25% sharpness per use.
Engine Degreasing: Apply Solvent Alcohol every 100 cycles to clear built-up organic matter and prevent catastrophic engine jams during combat.
Full Field Overhaul: Combine the damaged Gunsaw with 1x Titanium Ingot and 1x Repair Kit at any anvil to restore durability to 100%.

Pro-Tips for Gunsaw Users

Keep Extra Fuel in a Steel Flask: Store at least 2.0L of refined fuel in leak-proof containers from our Essential Bags & Containers Guide to avoid stalling mid-boss fight.
Feather the Throttle: Tap the attack button instead of holding it down continuously when clearing weak gravel tiles to conserve fuel and chain durability.
Emergency Revive in Sandbox: If testing weapon balance or mods in creative mode, spawn a Gunsaw instantly with spawn gunsaw cursor 1.0 1 using the Console Commands Guide.
