Acid Burn is a status effect in XCOM 2. Acid Burn will deal damage over time, similarly to Burning, but it does not confer any other effects to affected targets, and both biological and mechanical targets are equally vulnerable to Acid Burn.


  • Reduces health every turn by 1-3.
  • Biological and Mechanical units are both vulnerable, unlike other status effects. Only the Andromedon and a soldier wearing a Hazmat Vest/have the Fortress ability are immune to Acid Burn.

Causes Edit

  • Acid Burn can be caused by...
    • Walking over an Acid tile.
    • An Andromedon's Acid Bomb attack.
    • An Acid Grenade/Bomb.
