Description

Extra B was a summoner enemy that appeared in The Narratorium as a part of The Final Act Event. It had the same function as Breaker2. Upon death, it will spawn one Extra A, which has less health but is faster. The Extra A, when spawned, was temporarily invulnerable to all forms of damage. Because of it, the Extra B can easily overwhelm unprepared players.

Logbook Description

"The Extras are positioned throughout theater productions, serving as background characters in scenes and sometimes disguising themselves as objects to help move set pieces during transitions. They are typically assigned boring tasks that the Builder doesn't want to do, though their suffering is hidden beneath tear-painted masks."

Appearance

The Extra B is a dark creature which wears a light green suit with crosses on it and a white vest. On its head, it wears a white mask with golden accents and a light green hat.

Strategy

As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in The Narratorium is listed instead.

• Early-game towers like the Crook Boss, Golden Soldier or Golden Crook Boss are pretty useful here.
  • The Toxic Gunner and Electroshocker can be used to kill multiple at once.
• Later on, the Extra B becomes rather weak, meaning most towers should be capable of defeating them, including late-game towers like the Accelerator, Turret, Ranger or Pursuit.
