Corrupted Terror
Corrupted Terror was previously removed from the game on the 11th of October 2025 as it was part of the Halloween 2025 Live Events, though it has been made available through the Sandbox mode.
It is not accessible anywhere else in the game, aside from in Sandbox Mode. This page will attempt to include information about both the version before removal and its re-added version.
Description
The Corrupted Terror was a large, tough enemy that spawned in on Wave 6 of the Nil Zone and Nil Zone II as part of the Halloween 2025 Live Events and Halloween 2026 Live Events. It can currently only be accessed through Sandbox mode if the player has its Logbook. It had significantly higher health than every enemy before it while being slow to compensate. It always spawned with Stun Immunity and Freeze Immunity.
Appearance
The Corrupted Terror is a large entity with dark purple skin. It has multiple neon purple veins on its body. It does not have legs, instead having a black spine. On its left arm, it has a rusty metal claw while on its right arm it has an exposed bone. On its head, it has neon purple eyes and blackened teeth. It has multiple spikes and tentacles which are the same color as its skin on its body. It wears a rusty black helmet
Event 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 Nil Zone II is listed instead.
- High DPS towers like the Kingpin, Golden Crook Boss, Turret, Accelerator or Juggernaut should be used to take down the Corrupted Terror.
- Due to it having Freeze and Stun Immunity, towers like Freezer and Cryomancer cannot freeze or chill it, knockback towers cannot knock it back, while towers like Electroshocker, Warden and Trapper can only slow it down.
