TrenchLine:Tower Defense TrenchLine Tier Lists
Role-based meta for Easy through Hardcore after the Flood updates.
The Tier List Hub explains how TrenchLine:Tower Defense rankings work before you dive into the full Troop Tier List. Meta shifts when EasternEnthusiasts ships patches like v0.24.0 Flood Update and v0.25.0 FLOOD STAGE 2, so treat every letter grade as a snapshot tied to mode, map, and whether flyers or naval threats are in the pool.
TrenchLine is co-op zombie tower defense: you build trench lines, upgrade troops, and stop infected breakthroughs across Farmland Lake, Flooded Ruins, Frozen Channel, Breakwater Port, and Tidefall Beach. A unit that looks S-tier on Easy Farmland can be a trap on Hardcore Tidefall Beach if it cannot touch flyers or Brutes.
Ranking criteria
We weigh five practical questions:
- Wave coverage — Does the troop stay useful from early economy into late spikes?
- Role clarity — DPS, anti-armor, anti-air, economy, or naval specialist?
- Footprint and cost — Battle Tank’s four-block size is powerful but debated on dense trenches.
- Synergy — Farms plus Signaler plus FOB chains matter as much as raw DPS.
- Mode fit — Endless value differs from 40-wave Hardcore with Barnacle Behemoth.
Full letter grades and notes live on Troops Tier List. This hub maps the roles so you know what to look for.
Role primer
Economy
Farms, early Conscripts, and support pieces like FOB / Signaler / Troop Spawner fund everything else. Skipping economy to rush a Battle Tank is a common Medium wipe. Read Getting Started for the first ten minutes of income planning.
General DPS
Riflemen, Assault Squad, Marksman, and Spec Ops (Halloween unlock) clear Shamblers and runners. Spec Ops often overperform for their slot when upgraded, which is why they appear high on many community boards. Details sit in Troops and Best Loadouts.
Anti-armor
Armored infected and Brutes punish pure soft DPS. Community consensus highlights PKM as a strong armor answer and SPG-9 for its cone-shaped damage zone — place it so the cone covers the chokepoint, not empty grass. Battle Tank brings heavy firepower with a large footprint and contested cost efficiency after buffs in v0.23.0.
Anti-air (AA)
Flood-era flyers and gunship-adjacent threats need dedicated AA. Shilka and MANPADS Team are the headline answers; some ground troops simply cannot target air. If your lobby skips AA on Flooded Ruins or Breakwater Port, expect leaks. Cross-check spawn lists on Enemies.
Artillery and splash
Mortars, Rocket Battery, and SPG-style cones soften clumps before they hit the sandbags. Splash shines on Easy/Medium packed lanes and still matters when Drowned or Depth Chargers cluster on flooded routes.
Naval and Fleet Command
Boats, Rocket Barge, KPV, and related coastal pieces matter once Naval Tokens feed Fleet Command. As of v0.25.0, some Hardcore naval unlock paths are drop-gated — read Flood Event before you dump resources into a harbor you cannot supply.
Support and utility
FOB, Signaler, and spawners do not top damage charts but multiply the line. Grade them by how much they accelerate upgrades for PKM or Spec Ops rather than raw kill count.
Mode-by-mode meta notes
| Mode | Meta focus |
|---|---|
| Easy / Medium | Economy → balanced DPS; learn lanes without Hardcore bosses |
| Hard | Earlier anti-armor; tighter repair discipline |
| Endless | Sustainable farms and refreshable DPS; watch coin efficiency |
| Hardcore (Tidefall Beach) | Full kit — AA, armor, naval tokens, boss plan for wave 40 |
For the 40-wave specialist route, open Hardcore Tidefall after you finish the role primer here.

Frequently Asked Questions
Quick answers to the most common TrenchLine questions.
Where is the full troop ranking?
See the dedicated Troop Tier List for letter grades and per-unit notes. This hub explains roles and criteria first.
Is Battle Tank always worth buying?
Not always. It hits hard and occupies four blocks, so cost efficiency is debated. Prefer it when your economy and lane width support the footprint — details in Best Loadouts.
What counters armored infected?
PKM is a community favorite for armor, and SPG-9 rewards careful cone placement. Pair them with economy so upgrades arrive before Brute spikes.
Do I need anti-air on every map?
On Flood-era maps with flyers, yes — bring Shilka or MANPADS Team. Check Enemies and Flood Event for when air threats appear.
How often does the meta change?
After major patches such as Flood Update and FLOOD STAGE 2. Follow Updates and Patch Notes whenever EasternEnthusiasts posts balance notes.
