Siege Engine

"A siege engine?! This janitor must have been feeding them our classified information! Not good , they're more prepared than we thought!
Hold the line! We can't afford to have them get near the research outpost."

―Dispatcher on Wave 4 (Outpost 32)

Description

The Siege Engine, internally also referred to as Frost Spawner, is an enemy that only appears in Outpost 32 as part of the Operation I.C.E Event. Unlike other enemies in the event and even the game in general, it does not head to the exit and instead acts as the entrance for enemies to spawn from. It is still an enemy despite this, having its own statistics, an Index entry and even being affected by modifiers which apply hats to enemies like the Fireworks modifier.

It will kill units that collide with it and trigger road obstacles. As it drives on the path, it will run over all enemies in its path, killing them. It uses its own path instead of the regular one, though the main difference here is that its path takes a few shortcuts. This enemy is not required to be killed for waves to progress. While it has multiple attributes, they are all applied so that it is immune to as many sources of damage as possible and to prevent towers from attacking it.

Logbook Description

The Frost Spawner used in Outpost 32 to take down the Outpost's defenses. How did you get this anyways?!?

Appearance

The Siege Engine is a light blue siege engine, mostly empty except for a blue portal. When it moves on the path, the entrance will be obstructed, and a trail of wind will appear near it.

Strategy

• You do not need to kill the Siege Engine in most regular occurrences.
• If you need to kill the Siege Engine for the Logbook do note that it is extremely cumbersome and time-consuming.
  • You require the use of the Pumpkin Bomb removing the No Target and the God attributes. Therefore, it can only be killed on Outpost 32 Easy Mode, as Hard Mode does not permit the use of consumables.
    • The odds of this occurring is extremely low, so you will likely require multiple Pumpkin Bomb for these attributes to be removed.
  • Once God and No Target attributes are removed, you can set any towers to target last which will enable you to kill the Siege Engine, with the exception of the Accelerator, which is unable to target the Siege Engine, even with No Target removed.
    • Towers with long range, such as the Ranger, and the Pursuit are suited for this.
    • You can also use the Nuke to kill the Siege Engine, though the God attribute must be removed first.
    • After its killed, enemies will still spawn normally at where the Siege Engine was at before.
  • The Gatling Gun is unable to damage the Siege Engine without the use of the Pumpkin Bomb, even with FPS, due to the God attribute.
• In Sandbox Mode, if the player give the Siege Engine Boss attribute, its health bar will appear as 0/0 and will drive on the path towards the exit. After the Pumpkin Bomb removed the No Target and God attribute, its health bar will be displayed with its correct value, being 50,000.
