==Description==
The '''Null Engineer''', internally referred to as the '''Corrupted Engineer''', was a tanky enemy that appeared in the [[Null & Void Event]]. It was the first [[Boss]] enemy the player encounters. It had a high amount of health and a decent amount of [[Defense]], though it walks rather slowly. It has two abilities, both of which used to weaken towers and units.

The first ability is ''Attack'', where the '''Null Engineer''' targets either a tower, which results in it getting stunned for 1 seconds, or a random unit, which leads to it receiving 3,000 damage. The other ability is '''Spawn Turret''', where it creates a [[Null Sentry]] on the path. This [[Null Sentry]] will debuff a random. Both abilities have a range of 20, meaning they will not be used if there is no tower in range.

==Logbook Description==
"''When the Null Engineer emerged from the tear it caught Engineer's attention. She watched as the creature placed down a turret identical to her own. Engineer's jaw tightened as she pulled down her goggles. "Cheap knockoff," she muttered, goggles guiding her own turret as it whirred to life.''"

==Appearance==
The '''Null Engineer''' is a corrupted recreation of the [[Engineer]]. It has red skin and grey hair. Its left arm has been replaced with a prosthetic arm. It wears a black shirt, maroon overalls with yellow buttons, grey bandages, black shoes and a black glove. On its head, it wears a red hard hat with goggles on top. On its back, it has a small radio.

With its right arm, it wields a Attack which it uses to stun towers and damage units, while in its left, it holds a wrench used to make [[Null Sentry|Null Sentries]].

==Event Strategy==
As this enemy only appears through [[Sandbox Mode|Sandbox]] mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without [[Sandbox Mode|Sandbox]] mode in [[Blind Faith]] is listed instead.
*High DPS towers like the [[Ranger]], [[Pursuit]], [[Turret]] or [[Accelerator]] are recommended to take this down.
**While the '''Null Engineer''' does stun, this is not a large issue as the stun time is quite low, allowing towers which are not stun immune to still perform decently.
**The [[DJ Booth]] and [[Commander]] can be used to boost the statistics of these towers.
*As the '''Null Engineer''' initially spawns as a [[Boss]], most forms of stalling are ineffective against it and it cannot have its [[Defense]] reduced.
**For all of its future appearances, it only has the [[Stun Immunity]], meaning it cannot be knocked back and stuns will only slow it down.
