Nightmare Mode Mods (commonly called Nightmare Mods) are a class of rare dual-stat mods added in Update 9.0 (2013-07-13) along with Nightmare Mode. They can be acquired through completing missions in the Nightmare Mode. These mods are generally weaker than their single counterparts, but they can stack. For example,  Accelerated Blast can stack with  Shotgun Spazz and  Flechette to give 150% Fire Rate and 90% Puncture Damage respectively.

Update 9.5 (2013-08-09) introduced 3 new Nightmare mode mods ( Shred,  Vigor, and  Lethal Torrent) as rewards for the weekend event Arid Fear. These were later added to regular Nightmare mode missions as rewards.

The Update: Recurring Nightmares (2016-10-27) update for Halloween (October 27th to November 1st, 2016) introduced 3 new Nightmare mods ( Chilling Reload,  Drifting Contact, and  Streamlined Form) which were right away available to acquire in their respective nightmare missions.

During the Nightmare Weekend event (August 23rd to 26th, 2013), the 10 original Nightmare mode mods were also rewarded from special Alerts with a mission description of "Nightmare Mod Located".

Nightmare mods are untransmutable. Visually, they do not have a clearly distinguishing mark.

Trivia[]

• Briefly, between Update 12 and Update 12.1, Nightmare mods could be obtained from Interception missions. This was unintended, and has since been patched out.
• As of Hotfix 22.3.5 (2017-11-20),  Seeking Fury is also obtainable from missions level 26 and higher.
