Trench Decay Guides

TRENCH: DECAY drops you into a cooperative WW1 trench shooter on Roblox where four-player squads push objectives, survive poison gas, and extract before the line collapses. Every successful run feeds a Live War Map shared across all servers — your squad’s wins literally move the front. studio rook. ships the experience in early-access beta (BETA 1.1.x), so mechanics evolve patch to patch, but the fundamentals below stay consistent.

This hub collects every in-depth guide on the wiki. Start with Getting Started if you have never deployed, then branch into How to Play, controls, extraction tactics, gas survival, and map strategy as your squad levels up.

New player path

The fastest route from menu to competent squadmate:

1. Getting Started — account setup, Commissar tutorial, first loadout, and where to redeem codes.
2. How to Play — full squad loop, objective pacing, push vs hold decisions, and your first extract mindset.
3. Controls — sprint, crouch, lean, melee, block, inventory, and interact bindings on PC and mobile.
4. How to Extract — objective order, holdout timing, loot priorities, and the final push to friendly lines.

Skip straight to extraction if you already know FPS basics but keep failing the exfil timer — most beta wipes happen because squads treat extraction as an afterthought.

Combat and environment

Trench warfare is as much about terrain as gunplay:

• Survive Gas — mask discipline, route planning, and callouts when chemical attacks blanket no-man’s land.
• Live War Map — how server-wide progress works, why your deployment matters, and when to push versus consolidate.

Gas and map pressure interact: a squad that ignores chemical warnings may survive the immediate fight but lose map territory when they wipe before extracting.

Meta, economy, and opinion

Once you can extract reliably, shift from survival to progression and perspective:

• Enemies & Anomalies — PvE archetypes, melee closers, flank patrols, and how supernatural pressure pairs with gas.
• Medals & Crates — medals economy, Enlisted Cosmetic/Firearms/Melee crates, code payouts vs mission loot, and when to open rolls.
• Review — honest beta impressions: atmosphere, squad PvE loop, gas tension, Live War Map uniqueness, rough edges, and who should enlist now.

Medals and crate values on the wiki use community-reported framing — studio rook. can retune payouts silently between patches. Redeem active codes early and read Code Rewards before spending currency.

Pair guides with other wiki sections

Guides explain how to play; other categories cover what to unlock:

• Claim free medals and crates on the Codes Hub before grinding depot prices.
• Read How to Redeem Codes if Supply Codes rejects your input — studio rook. group membership is mandatory.
• Check Code Rewards so you open Firearms crates before Cosmetic rolls if you still have default weapons.
• Compare firearm and melee rolls against the Weapons Tier List after opening crates.

Progress saves during beta unless studio rook. announces a wipe. Re-read Getting Started after major patches — control defaults and tutorial steps sometimes shift in Preferences.

Squad etiquette for PvE

TRENCH: DECAY is online co-op, not solo-friendly extraction:

• Stick to role calls — one player watches rear gas lanes while others breach.
• Share ammo intel — Tab inventory checks prevent someone entering melee-only at the worst moment.
• Extract together — partial squad exfil leaves teammates fighting outnumbered and wastes Live War Map gains.
• Use voice or quick text — lean peeks (Q/E) only help if someone calls enemy audio cues.

When to revisit this hub

studio rook. labels the build BETA 1.1.x with frequent updates. After each patch note:

• Re-scan Controls for binding changes in Preferences.
• Confirm extraction objectives on How to Extract — beta sometimes adds sub-objectives or tightens timers.
• Re-read How to Play when spawn tuning feels different post-update.
• Watch for new milestone codes tied to map events or visit counts.
• Skim Review expectations if returning after a long break — beta roughness shifts week to week.
