Biochemical AnomalyEdit

Both the alien and adapted biogel have a 50% chance to cause one of ten random effects for 30 seconds.

The ten "Biochemical Anomaly" effects are as follows:



  • In some alien crates aboard Mothership Zeta.
  • It also can be found on alien workers and abominations.
  • Usually at least one found on a table in small rooms throughout the ship. These rooms are most likely living/dining quarters for the aliens.
  • Sally can provide 1-3 of these when asked if she's found anything on the ship after completing This Galaxy Ain't Big Enough....


It can be turned into adapted biogel by Elliott Tercorien, having it heal substantially more.
