Trench Decay Survive Poison Gas

Poison gas is the signature threat in TRENCH: DECAY — studio rook. markets the loop as “push the line, survive the gas, extract with your squad.” Chemical barrages punish squads that sprint in straight lines, ignore audio cues, or split during extraction holdouts. This guide covers warning signs, movement choices, squad communication, and how gas interacts with the Live War Map when repeated wipes stall front-line gains.

Pair this page with Controls for crouch, prone, and lean bindings, and Getting Started if you have not finished the Commissar gas introduction.

How gas works in beta

Gas zones behave like area-denial hazards layered on PvE combat:

• Visual fog — often greenish or yellow-tinged clouds rolling across no-man’s land or filling trench segments.
• Audio wind-up — artillery whistles or officer callouts frequently precede barrages; headset players gain seconds of warning.
• Damage over time — standing in open gas without protection drains health rapidly.
• Route blocking — clouds may cut the fastest path to objectives or extraction, forcing detours through side saps.

Exact mask item names and durations can change between BETA 1.1.x patches — verify in-game tooltips after updates. The survival principles below stay constant even if UI labels shift.

Pre-fight preparation

Before queueing a gas-heavy map segment:

1. Load meds — check Tab inventory; gas often compounds with bullet damage during holdouts.
2. Know your stance keys — C crouch/prone and X stand up let you crawl low under mixed wire/gas lanes (see Controls).
3. Assign a gas caller — one squadmate watches upstream wind direction and calls “gas left/right/back.”
4. Plan detour routes — identify parallel trenches on the map before the first barrage so you are not inventing paths while choking.

Cosmetic gas masks from Enlisted crates do not replace mechanics — but clear helmet silhouettes help callers spot who lagged behind during Code Rewards shopping sprees.

During a barrage — solo habits

When gas enters your lane:

• Stop sprinting blind — Shift sprint into unknown fog is the fastest wipe.
• Drop stance — crouch or prone to use lower trench geometry; some clouds sit higher in open craters.
• Lean before stepping — Q/E peek to see if the cloud ends around the next bend.
• Use kick (T) sparingly — create space if a teammate blocks a narrow exit, then immediately resume low profile movement.
• Interact (G) with cover — sandbags, corners, and door frames break line-of-sight with lingering clouds.

If the game provides a mask or filter consumable, activate before crossing the densest section — mid-cloud panic inventory opens get you killed.

Squad coordination

Gas kills teams that split without callouts:

Callout	Meaning
”Gas front”	Barrage inbound from objective direction — halt push
”Gas left/right”	Lateral drift — rotate detour together
”Masks on”	Consumable phase — no loot stops
”Through now”	Short gap — sprint burst as a four-stack
”Hold upstream”	Wait for cloud to pass before extraction interact

Extract together — if two players shortcut through gas while others detour, holdout phases start undermanned and fail. Read How to Extract for regroup timing at the beacon.

Gas during extraction holdouts

Holdouts often overlap with final barrages — worst-case scenario for public squads:

1. Pre-identify upwind cover inside the exfil zone before the timer starts.
2. Anchor stays in zone — chasing kills outside cover pulls gas into the group.
3. Flex carries spare meds — triage after crossing a cloud, not during it.
4. Block melee rushers (B) while gas ticks — elites push when you are vulnerable.

If the only route to the beacon crosses gas, delay interacting until the squad has masks or a timed gap — starting holdout mid-crossing is a common beta loss.

Route planning cheat sheet

• Prefer covered saps over open craters even if longer — damage ticks stack with sniper lanes.
• Follow allied tracers — prior squads on the Live War Map often wear predictable paths; learn from wiped teammates’ mistakes.
• Reset after gas clears — Tab check ammo before re-push; gas detours burn time and magazines.

Common gas deaths and fixes

Mistake	Fix
Sprint through for “speed”	Crouch-walk with caller timing
Split for loot	Regroup before crossing
Stand reload in open fog	Prone behind lip or retreat
Ignore audio cue	Lower music; listen for whistles
No meds after partial exposure	Heal before next firefight

Relation to codes and loadout

Gas survival is mechanical, not pay-to-win — but Codes Hub medals help you buy meds, masks, and Firearms crates faster. Redeem promos via How to Redeem Codes so economy does not slow your learning curve.

After patches, re-run one offline Preferences check and a low-stakes public squad to see if cloud density changed — studio rook. tunes horror frequently during early access.

Master gas and TRENCH: DECAY stops feeling like random death — it becomes a readable pattern your squad routes around while still pushing the shared front.
