Hack module

Hack modules were consumable multiplayer perks in Doom (2016) which functioned as a part of a player's loadout, with up to four hack modules being selectable at one time. Hack modules were unlocked randomly through multiplayer game play and came in three tiers&mdash;bronze, silver, and gold&mdash;reflecting the strength of their effects. The hack module mechanic was retired in update 6.66 and has been replaced with a new, non-consumable version of the single-player campaign's rune system, with runes which have effects similar to those which hack modules previously possessed. Hack modules were so-named due to the which serves as the explanation for the multiplayer mode's existence (that is, that the deathmatches take place inside a UAC virtual reality battle simulator).

Hack modules were divided into three categories: awareness, for modules which increase a player's alertness or reaction to nearby threats and benefits; boost, for modules which increase the player's health, armor, statistics, or abilities; and wallhack, for modules which allow awareness of normally hidden information such as the locations and activities of allies or opponents, regardless of their physical locations.
