Description

The Living Experiment is an enemy that appears in Intermediate, Challenge Trials and Molten Arena PVP modes. It also appears in The Takeover Event. It has a high amount of health, a below average speed and a decent amount of defense. Additionally, when it first spawns, it is a boss enemy, making it fully or partially immune to multiple forms of stalling. On some waves, it also spawns with various immunities, making it harder to kill.

Due to a bug, Living Experiments with the Slime attribute do not spawn the Slime upon death.

Appearance

The Living Experiment is a large humanoid with a waist, lower arms and lower legs in its rig. It has a light green skin color, and wears a tattered light blue hospital gown with a stitched seam going down the back, white bandages wrapped across its torso and metal plating with a glowing green piston on its back.

It has a thin right arm with an armband with chains on it, as well as a large bionic arm with multiple glowing green pistons and a green glass container. It also has a large metal neck-guard with glowing green parts, as well as glowing green eyes, patches of black hair and a metal device with green lights and light brown stitch lines surrounding it on its head.

It has a death animation, where it falls forward, with its bionic arm completely detaching in the process. The death animation is also accompanied by a sound, consisting of it grunting and metal thumping noises.

Strategy

  • Towers with decent DPS, like the Minigunner, Militant or Cowboy are recommended against this.
  • On its debut wave, the Living Experiment is surrounded by a hordes of Armored and Slows, which can be incredibly problematic.
    • Area of effect towers like the Pyromancer, Rocketeer, or Mortar can excel at clearing out the hordes, allowing DPS towers to focus on the Living Experiment itself.
      • Some of them like the Rocketeer and Mortar also have sufficient DPS to deal with the Living Experiment itself on their own.
  • As the Living Experiment has Defense, you can use Defense bypassing towers like the Trapper or Military Base to deal with this.
    • As these towers also have AOE attacks, they can be also used to deal with the hordes of enemies it usually spawns with.
  • Defense dropping towers, like the Pyromancer or Freezer can be used to reduce its defense, allowing your towers to deal more damage to it.
  • While the Living Experiment does not have any immunities to crowd control by default, it is a large enemy, making certain forms of stalling like freeze or knockback less effective on it.
