Horde Defenders Towers and Defense Roles

Horde Defenders ships with an 18-tower roster, but the official Roblox description only names the roles players meet first: Sentries, Railguns, Barricades, Barbed Wire, Tar Lobbers, and a howitzer called out in the marketing copy. Code drops also confirm Dreadnought and Stormcaller as live tower identities with skins. This guide organizes those confirmed tools into roles you can aim, so Scrap from Codes buys coverage instead of clutter.

Pair this page with the Tier List, the Early-Game Tier List, and High Ground. Manual aim rules everything — see How to Aim — so a “strong” tower still fails if you cannot keep the reticle on the column.

Confirmed tower roles (storefront + codes)

Damage workhorses

• Sentry — The day-one tracking gun. Place it on elevated pads that see the approach. Learn aim habits here before you chase exotic unlocks.
• Railgun — Harder single-target punch for elites, armored bugs, and bosses once your tracking is stable.
• Howitzer — Lobbed area damage. Lead moving packs into Barricade or Barbed Wire pockets; do not park the reticle on empty dirt.

Soft control and stalls

• Barricade — Creates a hard pause so your elevated guns have a stationary (or slower) sponge to shred.
• Barbed Wire — Line slow and chip that stretches time-on-target inside the kill cone.
• Tar Lobber — Ground control that slows approaches so prediction and tracking stay humanly possible.

Named heavies with skins

• Dreadnought — Appears in October 2026 code coverage via the SORRY skin reward. Treat it as a later flex damage piece once your funnel exists; cosmetics do not replace placement.
• Stormcaller — Likewise confirmed by SORRY skins. Use it when you already understand high-ground cones and strike timing from the Abilities Guide.

Horizon’s marketing also mentions “tens of thousands of alien bugs” flooding chokepoints — that fantasy favors overlapping cones, not twelve lonely Sentries on flat ground.

Soft-reported names (do not treat as facts yet)

Community posts and script listings sometimes mention Inferno, Hive, Nest, Burst Cannon, or Prismatic-style guns. This wiki keeps them soft-reported until you unlock them yourself on the live alpha build. Alpha naming can shift. Build with the confirmed list first, then expand.

How to spend Scrap across the roster

1. Secure one elevated Sentry that covers the natural path.
2. Add Barricade or Barbed Wire so bugs linger in that cone.
3. Upgrade the gun that is already aiming, not a second unfinished lane.
4. Add Howitzer or Railgun when early packs feel trivial but elites start leaking.
5. Bring Tar when prediction fails because packs move too fast through the gate.
6. Slot Dreadnought / Stormcaller after the funnel works and you have Scrap buffer for bosses.

Redeem GIBILOSTHISSCRAP and other Scrap-heavy codes before you invent a second base on the far side of the map. Economy detail lives on the Economy Guide.

Placement rules that matter more than rarity

• High ground first — elevated pads grant more range and damage (High Ground).
• One primary cone — your eyes cannot aim two distant lanes well on solo servers (server size 1).
• Control before vanity — Barricade and Wire often raise clear rates more than a cosmetic-heavy gun on flat dirt.
• Upgrade the funnel — Endless and late campaign punish unfinished gates (Endless Mode).

Heroes versus towers

Towers are the permanent aim surface. Heroes — Warden, Marksman, Sentinel — are force multipliers you can possess. Do not delete your Sentry line because a hero unlocked. Read Heroes Guide for possess timing that supports the same chokepoint your towers already cover.

Skins versus power

The SORRY code grants Dreadnought and Stormcaller tower skins. Skins are collection and clarity in the inventory UI. They are not a promise that those towers auto-win maps. Verify current rewards on Codes because alpha freebies expire.

Campaign and Workshop context

Across 59 levels and five alien worlds, bosses test whether your tower mix still covers the gate under pressure. Workshop maps may remove high ground entirely — then Barricades manufacture the choke. See Campaign Guide for world pacing and Alpha Status for bug expectations.

Practice checklist

• Rebuild a cleared early map using only Sentry + Barricade + one elevated pad.
• Add Wire and Tar; note how much easier tracking becomes.
• Introduce Howitzer into the pocket; practice leading.
• On a mid map, delete any tower that is not covering the primary cone.
• After redeeming skins, still audit placement before Endless pushes.
