- Trench Decay how to level up class: Earn XP by completing campaign chapters, surviving waves, and extracting loot alive.
- Pick one main class: Rifleman or Support levels fastest for most squads thanks to consistent wave performance.
- Extraction is the XP engine: Dying forfeits your haul — successful runs compound into faster class progression.
- Upgrade weapons between chapters: Reinvest credits into your class primary before pushing harder sectors.
- Squad composition matters: A balanced team earns more total XP than four players running the same role.
How Class Leveling Works in Trench Decay
Trench Decay how to level up class is one of the first questions new players ask after their opening deployment. Class progression in this WW1 squad PvE roguelite is tied directly to the core gameplay loop: hold the trench line against gas-fueled assaults, scavenge salvage, and extract with your haul intact. Every phase of that loop feeds experience into your active class, so the fastest way to level is simply to run the full loop successfully — over and over, with increasing difficulty.
Each of the six classes — Rifleman, Assault, Medic, Support, Engineer, and Scout — accumulates progression from the actions that define its role. Medics earn from revives and heals, Engineers from fortifications and demolition work, and combat classes from wave kills and objective holds.
| XP Source | What Counts | Best Class Fit |
|---|---|---|
| Wave kills | Enemies eliminated during defense phases | Rifleman, Support, Assault |
| Objective holds | Time defending trenches and strongpoints | Support, Engineer |
| Revives & heals | Teammates saved mid-run | Medic |
| Fortification work | Barricades built, wire placed, charges planted | Engineer |
| Successful extraction | Salvage banked at the extraction zone | All classes |
| Campaign milestones | Chapter completions and first clears | All classes |
Class XP leans toward role-appropriate actions. A Medic who ignores downed teammates to farm kills will level slower than one who keeps the squad alive. Do your job first — the XP follows.
Best Classes to Main for Fast Progression
Not every class levels at the same pace, and your choice shapes how quickly you unlock stronger loadout options. Based on performance across all six campaign chapters, these picks balance XP income, survivability, and squad demand.
Rifleman — Best Overall
- Reliable mid-range rifle works in every chapter
- High ammo efficiency means sustained wave performance
- Consistent kill XP from Chapter 1 through Final Stand
Support / Gunner — Fast Kill Income
- LMG suppression shreds grouped waves for bulk XP
- Ammo crates earn team-support rewards
- Dominates late-campaign defense chapters
Medic — Sustain Specialist
- Revive XP scales with squad wipes prevented
- Always in demand — squads rarely run without one
- Stays safest during gas pushes, surviving to extract
| Class | Leveling Speed | Difficulty | Best Campaign Phase |
|---|---|---|---|
| Rifleman | ★★★★ | Easy | Early to mid campaign |
| Support | ★★★★ | Medium | Late campaign defense |
| Medic | ★★★☆ | Medium | All phases, critical in gas pushes |
| Assault | ★★★☆ | Medium | Mid to late campaign assaults |
| Engineer | ★★★☆ | Hard | Objective defense chapters |
| Scout | ★★☆☆ | Hard | Early campaign and open maps |
Spreading playtime across all six classes slows everyone's progression. Commit to one main class until its loadout options mature, then branch out once your primary role carries harder content.
Step-by-Step Class Leveling Route
Follow this route to convert every deployment into maximum class XP. It works for solo players and coordinated squads alike.
Redeem codes and gear up
Redeem active codes for free currency before deploying. Spend starting credits on a decent class-appropriate primary and basic armor — early weapon upgrades make your first runs smoother and your kill XP steadier.
Clear Chapter 1 and 2 for foundation XP
Early chapters feature light infantry waves with slow trickle spawns. Use them to learn the trench layout, practice your class role, and complete first-clear milestone rewards, which pay out the largest single XP chunks.
Always extract, never over-loot
Extraction converts your salvage into war contribution and banks your run's rewards. Track the gas timer — if gas can reach your exit trench before you can, pull back one trench early. Dying means losing everything you carried.
Push higher chapters as your class matures
Chapters 3 through 6 introduce specialists, shielded units, and rapid gas timers. Your upgraded class loadout — LMG for Support, scoped rifle for Scout, medical kit tiers for Medic — should be ready before pushing these.
Reinvest and repeat
Cycle extracted salvage back into class weapon upgrades and utility tiers. Sustained contribution across consistent runs levels your class faster than one lucky deep push followed by a wipe.
A full squad extraction with a heavy haul out-earns a solo loot frenzy that ends in death. Consistency, not greed, is the real leveling strategy in Trench Decay.
Squad Strategies That Boost Everyone's XP
Trench Decay is built around squad play, and team composition directly affects how much experience every member banks. Squads that cover assault, sustain, and utility extract more often, survive later chapters, and level faster across the board.
The core principle: assign lanes, not fixed positions. Give each player a firing lane — left trench, center, right flank — so coverage stays intact when someone falls back, revives, or resupplies.
| Squad Role | Assignment | XP Contribution |
|---|---|---|
| Rifleman | Anchor center trench | Steady wave-kill XP |
| Support / Gunner | Chokepoint elbow with LMG | Bulk horde suppression XP |
| Medic | One trench behind the front | Revive and sustain rewards |
| Engineer | Flank routes and strongpoint | Fortification and demolition XP |
| Scout | Long sightlines on open maps | Priority-target pickoff XP |
Key squad habits that compound into faster class leveling:
- Revive in pairs: one player covers while the Medic revives — solo revives mid-wave snowball into full wipes
- Stack on one ammo crate during wave lulls instead of everyone carrying spare magazines
- Wire the flank routes — flanking raiders reuse the same side trenches every map
- Move on the gas surge, not before it — retreating early wastes loot time, late costs the run
Every successful extraction adds to the server-wide LIVE WAR map. As community progress fills war tiers, milestone rewards unlock for all participants — another steady income stream while you grind class levels.
Leveling Milestones Checklist
Track your class progression against these practical milestones. Clear them in order and your class will be ready for the late-campaign content that pays the best rewards.
Class Progression Milestones:
- Redeem all active codes and buy your first class primary upgrade
- Complete Chapter 1 and 2 first clears with a full squad extraction
- Memorize safe gas pockets and extraction routes in early sectors
- Unlock your class's core utility tier (ammo crate, medical bag, toolbox)
- Complete a Chapter 4 strongpoint defense without a squad wipe
- Extract from a Chapter 5 or 6 run with a full salvage haul
The DUAL update adjusted weapon balance and reworked map areas, including extraction routes. If you leveled a class before DUAL, run a lower-difficulty chapter first to relearn the changed routes before pushing hard extractions.
FAQ
Q: How do I level up my class fast in Trench Decay?
Focus on completing the full loop each run: hold your trench lane during waves, perform your class role, and extract with your loot alive. Successful extractions bank your run's rewards and contribute to LIVE WAR tiers, so consistent extractions level classes faster than risky deep pushes that end in death.
Q: Which class should I main as a new player?
Rifleman is the safest pick — its reliable mid-range rifle and high ammo efficiency perform well in every campaign chapter, giving you steady XP without a steep learning curve. Support and Medic are strong alternatives if you prefer suppression or sustain play.
Q: Do I lose class progress if I die during a run?
Dying means losing the salvage you carried, which cuts off that run's extraction rewards. Your existing class progression stays intact, but repeated failed runs dramatically slow leveling — extraction consistency matters more than loot greed.
Q: Does squad size affect class leveling speed?
Yes, indirectly. A balanced squad with assigned lanes survives later chapters and extracts more often, which means more banked XP per session for everyone. Lone players get surrounded and overrun quickly, ending runs before the big extraction payout.
