Field guide

Stonejaw were one of the first subspecies to be discovered on Icarus as a result of exotic mutation. Scientists have yet to confirm if its bite has been enhanced with venom due to contractors being eaten before they have the chance to inspect their wounds.

"Buggers get more and more pissed off until they explode at someone. Frustrating as HELL to deal with."
