File:Q2.png Brains (Beta class) is an upgraded version of Brains from Quake 2. In Quake II, Brains was a fairly useless Enemy as it was slow and only had melee attacks. Its one saving grace was an energy shield which protected its front end, same health as Gladiators, although even this was not enough to stop it being almost as pitiful as its predecessor. The Beta class, however, is a worse nightmare than the Laser Guard.
