The Trench Decay classes archive names Enlisted, Sapper, Quartermaster, Medic, Marksman, Defender, Engineer, Infiltrator, and The Decayed: community snapshot, current-version status: 待确认. This is a documented community roster, not an official announcement that the current game has exactly nine classes. The useful distinction between these entries is their described role and the action associated with skill-point progression, which are compared below.
01
Why the saved rosters show seven and nine classes
The community class index saved on October 2, 2026 contains nine entries, while an earlier overview dated August 22 lists the first seven: community snapshot, current-version status: 待确认. Infiltrator and The Decayed account for the difference between those saved lists. The archive dates establish what the research captured, but they do not establish when either class was released or whether a particular server has the same roster.
The official description in the research identifies Beta 2.6.3 and describes a squad PvE roguelite shooter. It does not supply a complete class list, class prices, or a skill-tree specification. Therefore, the official version label cannot be attached to every community detail as though the developer verified it.
02
Class roles and skill-point tasks in the archive
The following roles and progression actions come from the archived class index and are all community snapshot, current-version status: 待确认. They describe different ways of contributing, rather than a ranking from strongest to weakest. The task column identifies the kind of action recorded by that source, not a verified number of actions required for each skill point.
| Class | Role described in the archive | Recorded progression action |
|---|---|---|
| Enlisted | Survival, looting, and personal sustain | Collect dog tags |
| Sapper | Close combat and melee damage | Melee kills |
| Quartermaster | Ammunition supply and inventory support | Collect weapons, ammunition, or other items |
| Medic | Healing, sustain, and reviving | Heal or revive teammates |
| Marksman | Ranged damage and spotting | Headshot kills |
| Defender | Taking or blocking pressure for the squad | Take or block damage |
| Engineer | Construction and defensive structures | Place structures |
| Infiltrator | Stealth, marking enemies, and pistol use | Pistol kills or takedowns |
| The Decayed | Managing Decay as a combat resource | Kills, with a recorded Decay-stage condition |
03
Enlisted, Sapper, and Quartermaster
Enlisted is described as the starter class, with survival and looting themes and dog-tag collection as its progression action: community snapshot, current-version status: 待确认. Its entry also associates the class with submachine guns. That association is a role description, not evidence that other weapon types are prohibited or that every submachine gun receives the same bonus.
Sapper's archived identity centers on melee damage, with melee kills advancing its progression: community snapshot, current-version status: 待确认. The summary mentions life steal on a melee kill and an association with shotguns. It does not provide enough detail to turn those statements into a current healing amount, a complete shotgun build, or a universal recommendation for solo play.
Quartermaster is recorded as an ammunition and inventory support class whose progression involves collecting items: community snapshot, current-version status: 待确认. The index explicitly includes weapons, miscellaneous items, and ammunition in that action. It also associates Quartermaster with light machine guns, but does not explain whether repeated pickups, dropped items, or specific item categories are treated differently by the current progression system.
04
Medic, Marksman, Defender, and Engineer
Medic is described through healing and reviving teammates, while Marksman is described through ranged damage, spotting, and headshot kills: community snapshot, current-version status: 待确认. Their archived progression actions are different, even when both players are participating in the same fight. The saved overview supports that distinction but does not settle current revive timing, healing amounts, spotting duration, or the exact requirements of individual skill nodes.
Defender's entry records taking or blocking damage, while Engineer's records placing structures: community snapshot, current-version status: 待确认. The older overview shortens Defender's task to taking damage, so its wording should not be treated as a complete replacement for the broader archived index. Engineer's construction identity is documented, but these records do not verify every available structure, its cost, or its behavior in the present build.
05
Unlock conditions are not a universal price list
The general class page records a level requirement before classes become available and describes Medal purchases with exceptions: community snapshot, current-version status: 待确认. However, the separate Infiltrator page identifies a named Warbond route that the general pricing sentence does not clearly reconcile. For that reason, this guide does not convert the overview into a current price for every class or promise that reaching one shared threshold unlocks the entire roster.
For a specific class, the unresolved question is its own displayed requirement, not simply whether another class was purchased successfully. The official statement about free-play unlocks covers weapons, gamepasses, and cosmetics without publishing a complete class purchasing table. The archived class names remain useful search and menu identifiers, while exact current prices and access conditions remain 待确认.
06
Infiltrator and The Decayed have separate records
The Infiltrator page says the class is obtained through the Unrecorded Service Warbond and earns skill points from pistol kills or takedowns: community snapshot, current-version status: 待确认. That page is explicitly marked as a stub, with its skill rows and ultimate left empty. Those blank sections cannot support an invented stealth duration, takedown requirement, damage bonus, or full skill build.
The Decayed page records either reaching level 100 or obtaining The Guardsmen or The Imperium Marines Warbond as access routes: community snapshot, current-version status: 待确认. It describes kill-based progression and says kills count double at Decay Stage 3 or above. Those conditions belong to the archived entry; they have not been confirmed through current in-game testing or a matching official class announcement.
The Decayed's saved skill text names Rot In The Blood, Rot Burst, Bloodlust, and Rot Unbound: community snapshot, current-version status: 待确认. Those descriptions connect the class to building or spending Decay, melee-kill sustain, and a temporary ultimate effect. The archive contains additional percentages and cooldowns, but repeating them as a current build would exceed the evidence available here.
07
Mode rules and the limits of a best-class answer
The class index says Modern Defense offers class-specific equipment selections, while Classic Defense and Offensive use the player's inventory kit: community snapshot, current-version status: 待确认. That distinction matters when comparing a class description with a weapon recommendation taken from another mode. The archive does not establish the complete present-day selection for each class, so a named weapon in an older loadout is not proof that it is selectable everywhere.
There is no tested universal best class in these saved records. What they do establish is a set of named community roles, differing progression tasks, and specific conflicts that prevent a definitive current roster or price table.
