Beedubs

Beedubs, also known as Bioweapons or colorfully as 'Vat Bastards', are products of experimentation by megacorporations, rogue elements, or military organizations to create viable killing machines. Often they prove successful. They are massive threats to the public at large, and have been officially banned throughout the world. That hasn't stopped their production, however, as most ignore the ban.

They vary largely in what they are capable of, as well as in the manner of their elimination. If engaged, discover their weaknesses, and put them down before they put you down...or they decide to do something far worse to you.
