Notes[]

  • Alpha Constructs last for 30 seconds, or until killed.[1]
    • However, the timer is reset and paused as long as the player is within 100m of the ally.[2]
  • Due to the global ally limit, high stacks of this item may prevent other allies from spawning, e.g., Empathy CoresEmpathy Cores
    Recruit a pair of Solus Probes that gain power with more allies.

Turrets must be the ones to land the killing blow on Elites to spawn their own Alpha Constructs, however.

Lore[]

"Excellent!  How did you find it?"

"We took down one of those floating fortune tellers--"

"Xi Construct."

"Sure.  Anyway, we took it down and recovered the sample."

"May I see it?"

"This is it."

"This?  What happened?  I thought you said it was glowing."

"That's right.  It was.  Before I scrapped it."

"...You ...what?"

"I scrapped it."

"You were finally able to recover a sample from the Xi Construct, and you scrapped it?  Do you realize monumental importance of the samples we've been gathering?"

"I realize the monumental danger.  I've read the lab files.  Daimera's crippled in one hand.  Veirs was THIS close to electrocuting herself.  After Fitz nearly KILLED his ENTIRE team for a VASE, you think I'm going to haul a mysterious glowing orb back here?  HELL.  NO."

"...Well, what's done is done.  I guess I'll analyze what's left.  Anything else?"

"Yeah, I was thinking we could call it a 'Defense Nucleus'."

"..."

"In the file."

"No."
