Hack to the Future II

Hack to the Future II is the fifth Doom Eternal event, extending from July 2 to August 6, 2020. Its items belong to Series 4. This series was later reprised as Last Chance: Hack to the Future II between September 9 and September 16, 2021. After that point, the contents of the series were re-assigned to the premium Doom Eternal: Series Four Cosmetic Pack and will no longer appear as part of the event rotation.

This series is notable for containing references to the Doom RPG series. In particular, the "Fiend" and "Ghoul" revenant skins explicitly re-create the fiend and ghoul enemies from that series. The "Blue Flame" arch-vile skin also strongly resembles the apollyon. The upgradeable "Classic" podium featured in the Retro Master Collection additionally uses graphics from classic Doom.

The name of this event is an allusion to the 1989 motion picture .
