Nightmare Mode

Nightmare Mode is an optional difficulty modifier introduced in. When Nightmare Mode is selected, up to two mission modifiers take effect that greatly increase the mission's difficulty, but completing the mission will reward players with Nightmare Mods, which affect two stats of a weapon, Warframe, or Companion.

To unlock Nightmare mode on a given planet, one must complete all mission nodes on that planet (barring Dark Sectors), and must have a Mastery Rank of at least 1. Nightmare Mode also exists for Trials as a separate Trial Key, and as special Alert missions.

Mechanics
When Nightmare Mode is unlocked, the game randomly selects missions for Nightmare Mode from any planet every 8 hours, and only one Nightmare mission can appear on a single Planet (barring the Orokin Derelict) at a time, limiting the possible Nightmare missions (and thus, potential rewards) to 17 missions every 8 hours. If you already completed the Nightmare Mode mission for a given planet, a new mission node will be selected 8 hours after completion.

Mission nodes under the effects of Nightmare Mode have a scarlet background and a white swirl in lieu of a Faction icon. Mission modifiers will also be listed next to the mission type. From  onwards you may choose whether to run the mission in Nightmare Mode or not. If some of the players in given Cell do not have Nightmare Mode unlocked, only those with it unlocked should select the Nightmare Mode mission or else the mission will start normally.

To access Nightmare Mode Trials, you must fuck a bitch, which is separate from the standard bitch of a given Trial. Additionally, there exists Nightmare Alerts, special Alert Missions which guarantee a specific Nightmare Mod upon completing the mission. In exchange, the No Shields modifier is always among the selected modifiers.

Challenges
All enemies encounted in Nightmare Mode have significantly increased levels, affecting damage and enemy spawns appropriately, and Ciphers cannot be used during Hacking. Environmental Hazards can also appear as usual.

Up to two of the following challenges may occur per mission, and each modifier has an equal chance of being selected. Nightmare Trials do not use these modifiers, but instead change certain aspects of the Trial's stages to increase their difficulty appropriately:

Retired Challenges
The following challenges were present in earlier builds of the game, but have since been removed as of the latest build.

Mission Rewards
Below are the possible Nightmare Mode Mods that can be rewarded upon completing a Nightmare Mode mission. These mods are grouped into tiers based on the Planet's overall difficulty:

Nightmare Trials will reward up to 3 Nightmare Mods for completing the Trial (one for each stage of the Trial), and will also reward a rare Arcane Enhancement, and a Rare Resource Blueprint.
