Holographer

The Holographer usually tries to protect his allies, or himself, with a shield. Their shield is a holograph which is able to block bullets. They aren't dangerous if they are close to you like a 1v1. However, when he's protecting a Pistolian you should be taking down that shield. The only thing not carried from Slicers are that Holographers can't charge like Slicers do, but they can bash which would give them a boost while hurting enemies in front of the shield which is their normal attack. Holographers rank up to a Pistolian which are aliens with a pistol.
