Unstable Ice (Operation I.C.E) was previously removed from the game on the 15th of January 2025 as it was part of the Operation I.C.E Event, 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 Unstable Ice was an enemy that appeared in Outpost 32 as part of the Operation I.C.E event. It currently only appears in Sandbox mode. It has a decent amount of health and moves at a fast speed. It also has the Freeze Immunity, meaning that it cannot be frozen or chilled by freezing towers. After dying, it will use its Avalanche ability, which makes it jump upon at a tower or unit in its range, exploding and freezing everything in a range of 5. If there are no towers or units in range or only towers that cannot be targeted, it dies normally.

Logbook Description

"After a massive avalanche, the sudden compaction of energized snow sparks new life as an Unstable Ice. Lopsided with thick shards protruding from its body, the Unstable Ice can often be found roaming the lower mountain side. The energy from the avalanche is stored within their body and explodes out after death, freezing towers and units."

Appearance

The Unstable Ice is an entity with white skin covered in a thick layer of blue ice. It has one white eye on its head. While it has a large torso and waist, its legs and arms are thin. It has additional layers of snow on its shoulders and torso, which have blue spikes protruding from them. Inside its body, it contains energy from a massive avalanche which is released upon its death.

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 Outpost 32 is listed instead.

• High DPS towers like the Pursuit, Ranger or Accelerator are useful here.
  • As the Ranger and Pursuit have quite high range, they can easily stay away from the Unstable Ice, making them less likely to be frozen. The Pursuit also cannot be targeted by it.
• The Field Medic can be used to grant your units immunity to being frozen.
  • This is not the case for the Medic, however, as it is unable to cleanse freeze from towers.
