There are different types of Cybermen in this content for Fallout 4. The page dedicated to the mod, in fact, says that the Reject Cybermen are "those unfortunate souls whose 'update' conversion was imperfect, left abandoned, usually found among the Feral Ghouls". The dilapidated supermarket, on the other hand, could house a few free Cybermen fueled only by anger. The heavy variants, finally, are essentially a fusion of Fallout's power armor and Doctor Who's Cybermen.
To make everything less monotonous, the modder RascalArt has also inserted a series of holotapes. These can be found on the corpses of slain Cybermen. The drops are random but the tapes delve into the story of a scientist, his dreams and projects. The designs of the Cybermen are taken from the era of the 10th Doctor, taking a cue from stories such as Age of Steel which gives the mod its name. The enemies of this generation differ in that they are more armored and tank-like than the more elegant models of the Moffat and Chibnall eras. The Heavy and Rejected variants, on the other hand, are unique designs that are closer to the Fallout 4 universe than to that of Doctor Who.
