~ Hans Bichenbach, Head of the Citadel Station Biology Department
Inviso-Mutants appear as small, translucent, stingray-like creatures and are exclusive to the Maintenance Level of Citadel Station. They are similar to Zero-Grav Mutants, as they fire projectiles, but pack a much bigger punch. 3 or 4 hits from them is usually enough to kill the Hacker.
Being relatively flat, these mutants are hard to hit with firearms and on top of that are quite resistant to bullets. With it being almost completely dark, they pose a serious threat until you get the Lantern and Laser Rapier. They will easily take half of a Minipistol clip to die. Don't even bother with the Dart Pistol or SparqBeam, unless you can fire from cover, or you'll be open to damage. Upon entering the Maintenance Level, the highest priority should be locating the laser rapier.
