TrenchLine:Tower Defense Guides & Walkthroughs
From first trench to Hardcore Tidefall Beach — every playbook in one place.
Welcome to the Guides Hub for TrenchLine:Tower Defense, the co-op zombie tower defense from EasternEnthusiasts on Roblox. These walkthroughs cover day-one controls, mode selection, map geometry, Flood-era naval play, Naval Tokens, and endgame Hardcore routes. Each guide links out to roster data, tier lists, and patch context so you never read a tip in isolation.
TrenchLine launched around 2 October 2026 as a free Strategy / Tower Defense experience with Moderate maturity, online co-op, and servers up to 25 players. You dig in, place troops, upgrade under pressure, and hold the line against Shamblers, runners, armored infected, Brutes, flyers, and worse. Use this hub as the table of contents, then open the child guide that matches your goal.

Beginner path (first session)
- Skim Getting Started for lobby flow and what to buy first.
- Play Easy on Farmland Lake to learn chokepoints without Hardcore bosses — see Maps.
- Read How to Play so you understand why repair order and lane width matter more than spamming tanks.
- Check Troops so Riflemen, Farms, PKM, and SPG-9 are not mysterious icons.
- Glance at Codes — there are no working codes as of November 2026, but redemption steps are documented for when EasternEnthusiasts drops one.
Intermediate path (Hard and Endless)
Once Easy feels stable, move into Medium and Hard. Bring earlier anti-armor, respect flyer warnings on flooded layouts, and stop overbuilding Battle Tanks before your economy breathes. Best Loadouts translates the Tier List Hub into concrete shopping orders. For marathon sessions, Endless rewards farms and refreshable DPS more than one-shot greed.
Console players: v0.23.0 added controller support. The same guide advice applies; only the input layer changes.
Flood and naval path
v0.24.0 Flood Update and v0.25.0 FLOOD STAGE 2 (noted around 7 November 2026) expanded water maps — Farmland Lake, Flooded Ruins, Frozen Channel, Breakwater Port — and pushed boats, flyers, Depth Chargers, and Naval Token sinks into the spotlight. Read Maps for geometry, Flood Event for systems, and Naval Tokens for the Hardcore-only Fleet Command economy after Stage 2. AA pieces (Shilka, MANPADS Team) belong on the line when gunships and flyers appear.
Pair Flood reading with Enemies so Drowned, Depth Chargers, and Sand Worm timings are not surprises.
Hardcore path
Hardcore — Tidefall Beach is a 40-wave gauntlet capped by the Barnacle Behemoth. Do not queue it until you can explain your AA plan, armor plan, token spend plan, and economy plan out loud. Hardcore Tidefall walks wave breakpoints and boss prep; Naval Tokens covers Tokens page timing. Cross-link Patch Notes after every balance tweak — Battle Tank, SPG-9, Farms, Marksman, and Gunship rockets have already shifted.
How these guides stay accurate
- Facts stay aligned with Updates after EasternEnthusiasts publishes version banners.
- Roster names match Players (Conscripts, Marksman, Assault Squad, FOB, Signaler, Rocket Barge, KPV, Troop Spawner, and more).
- Optional automation notes live under Scripts — never a substitute for reading How to Play.
- Site-wide navigation is mirrored on the Wiki overview.
Guide writing standards on this wiki
Every guide aims for practical steps, internal links with trailing slashes, and FAQs that match real search queries (how to unlock Fleet Command, how to beat wave 40, what to buy first, which map to practice). We avoid filler and outdated code rumors. When a mechanic changes, we revise the child page and leave a pointer from this hub.
