 The inside front covers of the limited series featured 'in-universe' text pieces (such as memos from the fictional Nakasoni Corporation) that established links between Digitek and the other Marvel UK titles (such as "Warheads" and "Genetix") - these documents were not reprinted in the "Overkill" anthology.At the time, this was a standard publication method for Marvel UK, with the intention that "Overkill" would be better suited to the UK market, whereas the 'standard' Marvel format would be better suited to comic shops in other countries.As with most of the other Marvel UK titles, Digitek also attempted to attract existing Marvel Comics fans by including a prominent Marvel character in the initial storyline - the cyborg Deathlok.
