Alien Grunt

Appearance
Alien Grunts are large bipedal alien from Xen, sporting stocky builds and the classic vestigial chest-arm. They both stand further upright and sport more armor than their cousins in Half-Life, but are just as dangerous. A-Grunts serve as Elite Troops and are observed to have a higher standing than Vortigaunts within Xen. This superior status can be attributed to the fact that they are produced in cloning factories as seen in Interloper.
