―Commander on Wave 11 (Outpost 16)

Description

The Null Freezer, internally referred to as Corrupted Freezer, was a support enemy that appeared in Outpost 16, Banlands and Blind Faith as part of the Null & Void Event. It had a decent amount of health and a rather fast speed.

The Null Freezer had one ability where it throws a neon blue snowball at a tower or a unit in its range of 20. This will freeze any tower for 2 seconds or damage units by 400 if hit by its small explosion.

Logbook Description

"The Nil Zone's creatures defy all logic. When the God Shard experiment failed, the fabric that separated the Nil Zone tore, allowing it to replicate the Overworld. Creatures morphed into Freezers with the ability to stun any tower they fired upon. For the original Freezer, it was like staring into a corrupted mirror."

Appearance

The Null Freezer is a corrupted recreation of the Freezer. It has purple skin. It wears a purple shirt, pants, beanie and shoes. It has purple fur around its neck and a bag on its back. Tendrils can be seen coming out of its bag and around its head. It also has knee-pads and a small plate on its left arm. What appears to be purple goo can be seen on its hands and feet.

In its hands, it carries a neon blue snowball which it throws at towers and units.

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 16, Banlands and Blind Faith is listed instead.

• Towers with decent DPS like the Golden Scout, Rocketeer, Minigunner and Accelerator are quite decent against the Null Freezer.
  • Towers which are placed multiple times are especially useful here, as the explosion is quite small. This means only one tower or unit will be hit on average, which hurts low placement towers like Turret or Gatling Gun far more.
• As the Null Freezer freezes towers, towers immune to stuns are not immune to its freeze.
  • While the Pursuit does have the Freeze Immunity, it does not work and it still gets frozen regardless.
• Units that do not stop moving are quite effective against the Null Freezer due to its horrible aim. As it will aim at where it stood originally, it will miss any moving unit, making them basically immune to its attack.
  • This makes towers like the Mercenary Base, Military Base and Necromancer useful against it.
  • Units that stop to move or are stationary however, are pretty ineffective as they will always be hit by it. Such units include the Rifleman, Biologist plants and Crook Boss goons, though as a lot of them will be spread out rather than stacked in one place, only one will be hit generally.
  • Interestingly, It will also target units still in their death animation as long as the actual model has not disappeared yet.

Trivia

• While the Null Freezer can actually hit multiple towers or enemies at once, this is extremely unlikely to happen as its size means the units or towers basically have to be standing in one spot.
• The Null Freezer is unaffected by enemy appearance modifiers, such as Talk Like a Pirate Day.
