Dummy Defense Undead Mode: Bosses and Rewards Guide

Undead Mode is an expert challenge where players defend against the Undead Faction across waves of sprint runners and armored variants. Clearing the mode requires defeating the Plague Doctor boss, which unlocks the Sphere Dummy, a lobby lore tape, and a player tag.

What Enemies Spawn in Undead Mode?

The Undead Faction is a specialized enemy lineup introduced in update V1.29 that opens with fast sprinting attackers. According to the Dummy Defense enemies guide, the mode opens on wave 1 with the Infected Dummy, an unarmored unit that moves at speed 6 with 13 health and relies on rapid swarm pacing rather than heavy defenses.

Subsequent waves introduce four additional infected variants added in the October 1, 2026 balance update:

• Void Dummy
• Void Scale Dummy
• Armored Infected Dummy
• Husk Mutant Dummy

These units apply pressure by combining sprint speed with armored health pools. Defenses that rely on slow single-target attacks struggle against the opening rush, making early damage coverage necessary to handle swarms before tankier variants reach the lane.

Dummy Defense groups its match types into Normal and Special modes, then hides two more behind map tricks and vote menus.

How Do You Defeat the Plague Doctor?

Plague Doctor is the final boss encounter of Undead Mode that appears at the end of the match. Defeating this boss requires steady damage output that can burn through high health totals while remaining active through multi-lane wave pressure.

Unlike standard wave runners, the Plague Doctor functions as a standalone boss encounter with its own dedicated encounter rules. Successful setups enter the boss wave with high-damage towers placed along overlapping firing zones, supported by the automated systems unlocked from earlier campaign clears. Players who bring unlocked player abilities from noob battalion clears can deploy Gold-purchased utility like airstrikes or barriers to control pacing during the boss fight.

Which Mode Unlocks Should You Complete First?

Early mode progression is the intended path before attempting late-game encounters like Undead Mode and experiment mode. As detailed in the Dummy Defense gamemodes guide, clearing standard difficulty maps activates operational mechanics that improve match efficiency:

Completing Team Guest gives immediate access to the automated wave skipper in the lower corner of the screen. Controller Mode adds higher base speed settings to standard matches. Tackling Undead Mode after securing these systems reduces match management overhead.

What Rewards Do You Earn From Undead Mode?

Badge rewards are permanent progression milestones awarded after clearing the final boss wave. Defeating the Plague Doctor grants the official Defeat Plague Doctor badge, which does not expire and awards three account unlocks:

1. The purchase right for Sphere Dummy in the unit shop.
2. A collectible lore tape formatted for the lobby television set.
3. A unique profile tag displayable in match lobbies.

According to the Dummy Defense badges guide, these milestone items cannot be purchased with Bricks or account levels alone. Earning the clear on Undead Mode provides the sole route to add Sphere Dummy to your defense roster, making the Plague Doctor encounter an essential milestone among mid-to-late badges collection routes.
