Quick Guide
  • Trench Decay Cerberus is one of the campaign's most dangerous special enemies, appearing during late-chapter wave pushes.
  • Gas timing decides the fight: Cerberus pressures alongside gas surges, so position near safe pockets before engaging.
  • Best counters: high close-range burst (shotguns) for breaches, LMG suppression for lane control, and Engineer barricades to slow its approach.
  • Squad rule: assign firing lanes, revive in pairs, and rotate fresh defenders onto the corridor every wave.
  • Extract early: dying to Cerberus means losing your entire haul — leave before the final gas advance if the fight turns.

Cerberus Overview: Threat Profile

In Trench Decay, the Cerberus is a heavy frontline enemy that leads sustained siege waves, typically in the later chapters of the campaign such as The Strongpoint and The Breakthrough. It functions as a shock unit: high durability, aggressive forward pressure, and the ability to force squads out of fortified positions. Because it pushes during gas surge windows, fighting it is as much about positioning and timing as raw damage output.

Video Highlights (official trailer — core combat loop reference):

  • Squad-based WW1 trench defense against escalating waves
  • Gas-driven pressure that shrinks the playable sector
  • Loot, hold the line, and extract with your haul intact
AttributeThreat LevelNotes
Durability★★★★☆Heavy armor class; sustained fire required
Close-range pressure★★★★★Shreds unfortified trench sections quickly
Speed★★★☆☆Steady push, faster during gas surges
Squad wipe risk★★★★☆Punishes scattered, uncoordinated teams
Counter difficulty★★★☆☆Manageable with chokepoints and barricades
Watch the Gas Timer

Cerberus pushes are scheduled alongside poison gas surges. If the gas indicator shows an incoming surge, reposition to a safe pocket or trench elbow before engaging — fighting Cerberus inside advancing gas is the most common cause of full squad wipes.

Attack Patterns & Weaknesses

Cerberus applies pressure through three core behaviors. Learning to read them is the difference between a controlled kill and a panicked retreat.

PatternWhat It DoesBest Response
Forward pushAdvances steadily into your trench line, forcing defenders backBarricade chokepoints, concentrate fire at trench elbows
Breach attemptTargets weakened or unrepaired barricade sectionsEngineer repairs between waves; wire the flanks
Gas-surge synergyAttacks escalate right as gas advancesPre-position near safe pockets; never fight mid-retreat

Key weaknesses to exploit:

  • Funnel dependence: it performs poorly in tight, barricaded corridors where only one approach exists.
  • Sustained fire vulnerability: LMG suppression from a fixed tripod position melts its armor over a full wave.
  • Isolation during reload windows: coordinated pushes between its attacks create safe damage phases.
Pro Tip

Set up at a trench elbow — corner junctions give you cover on two sides and a single approach to watch. Let Cerberus funnel into overlapping fire lanes instead of fighting it in the open.

Best Weapons & Squad Loadout

Weapon choice against Cerberus follows the same tier logic as the rest of the game's arsenal. Prioritize burst damage and sustained suppression over mobility picks.

Shotgun (S-Tier)

  • Very high close-range damage
  • Deletes breach attempts at chokepoints
  • Best paired with Assault class holding the funnel

LMG (S-Tier)

  • High sustained damage, large magazine
  • Holds lanes solo during heavy waves
  • Set up at the strongpoint choke on a tripod

Scoped Rifle / DMR (A-Tier)

  • High per-shot damage
  • Pick off Cerberus early before it closes distance
  • Scout marks targets for team priority
ClassRole vs. CerberusKey Utility
Support / GunnerPrimary damage dealerAmmo crate resupplies the whole squad
EngineerChokepoint controlBarricades, barbed wire, satchel charges
MedicSustainStay one trench back; revive in pairs
Assault / RaiderBreach cleanupSmoke crossing, close-range finisher
Scout / MarksmanEarly pressureFlare-mark the Cerberus for focus fire
Loadout Rule of Thumb

Bring at least one LMG for suppression and one shotgun for the funnel. A squad without sustained fire will run dry mid-push; a squad without close-range burst gets breached at the barricade.

Step-by-Step Fight Strategy

1

Pre-build the chokepoint

Between waves, have your Engineer stack barricades and barbed wire on the flank routes Cerberus uses. Wire buys seconds of warning and slows the approach to a crawl.

2

Mark and pre-aim

When the wave starts, the Scout flare-marks Cerberus so the whole team prioritizes it. Support sets up at the trench elbow pre-aiming the spawn funnel.

3

Suppress at range

DMR and LMG fire open the damage phase while Cerberus is still crossing open ground. Every meter it loses before reaching the trench is free damage.

4

Hold the funnel

As it closes, concentrate shotgun and LMG fire at the single barricaded approach. Repair between waves — never let the funnel degrade below full strength.

5

Manage the gas surge

When the gas indicator triggers, rotate the squad to the nearest safe pocket or dugout while keeping overlapping fire lanes on the funnel. Move on the surge, not before and not after.

6

Extract with margin

Once Cerberus falls and the wave breaks, start the extraction corridor rotation. Arrive as a squad, defend the zone hold timer, and never sprint in solo.

Don't Get Greedy

Dying means losing everything you carried. If the fight turns bad — barricades down, medic dead, gas closing — cut losses and extract. A successful extraction still contributes to the LIVE WAR map; a wipe contributes nothing.

Pre-Fight Checklist & Common Mistakes

Before the Cerberus Wave:

  • Full barricades and barbed wire on both flank funnels
  • Ammo crate placed at the trench elbow
  • At least one S-tier weapon (shotgun or LMG) in the squad
  • Gas timer checked and nearest safe pocket identified
  • Extraction route corridor barricaded from the start
  • Lanes assigned: left trench, center, right flank
MistakeConsequenceFix
Fighting in the openSquad surrounded and overrunOnly fight from trench elbows and chokepoints
Solo revives mid-waveOne down snowballs into a full wipeOne covers while the medic revives
Retreating late from gasRun lost with the entire haulPull back one trench early every run
Skipping barricade repairsCerberus breaches the funnel unopposedRepair between every wave
Last-second extractionCaught alone by shock wavesLeave with time to spare, as a squad
Consistency Beats Heroics

Sustained contribution across runs matters more than a single big haul. Even a partial extraction pushes the server-wide LIVE WAR frontline forward for everyone.

FAQ

Q: Where does the Cerberus appear in Trench Decay?

Cerberus-class heavy enemies lead sustained siege waves in the later campaign chapters — The Strongpoint and The Breakthrough — and can appear in final-stand defense waves where all specialist types push together.

Q: What is the best weapon against Cerberus?

A heavy close-range shotgun for funnel defense and a high-capacity LMG for sustained suppression. The LMG shreds armor over a full wave while the shotgun handles breach attempts at the barricade.

Q: Can I fight Cerberus alone?

It is strongly discouraged. Trench Decay is built around squad play — assign firing lanes, revive in pairs, and rotate defenders. Lone players get surrounded and overrun quickly against heavy pushes.

Q: What happens if I die fighting Cerberus?

Death means losing what you carried on that run. Everything you extract successfully converts into war contribution on the LIVE WAR map, so cutting losses and extracting early is often the smarter play.
