Corrosive Acid
| Expels acid onto an object or wall, destroying it after a while. If used on wall, a hole will appear after some time. Small xenos can climb through, large xenos can break the wall with the hole on it open. CTRL + click to interact with the acid hole.
During the prep phase, all xenomorphs with this ability get strong acid.
