Operation Black Nightmare

Operation Black Nightmare is the second operation to come out, along with the first mission with an NPC to control. The squad assigned for this operation will have to eliminate the numerous Chaos Insurgents stationed in the base and rescue a captured O5 Council member, as well as destroying enemy anti aircraft armament.

Briefing
''By the order of the O5 Council, this mission is classified Clearance Level 5. The Council has also designated this operation as a Level 7 emergency, failure cannot be tolerated. The Intelligence Agency has discovered a nearby base where O5-4 was taken. Satellite imagery proves there is a base of operations located here, which we can presume is the Chaos Insurgency's. Your mission here will be to rescue the O5 Council member. However, due to multiple anti-air defensive systems, we are unable to deploy you to the ground. You're going to need to parachute in.''

Overwatch, we've arrived.

Operatives, prepare for exit.

Initial
The squad is deployed outside of a mineshaft via parachuting off of ACE's Chinook that leads into the base. They are tasked with locating O5-4, clearing out anyone hostile (being the Chaos Insurgency patrolling the base) along the way.

Mission Update 1
Once O5-4 is located in a solitary cell, the squad is tasked with leading him back to the surface, having to deal with reinforcements along the way. However, the O5 has to get his revolver and documents from the base armory in order to proceed, which he'll do once the squad has entered the armory.

The squad encounters a quarantined sector of the base, having to put on emergency respirators along with the O5 in order to proceed without issue. They'll face instances of SCP-008 until they've reached the elevator leading to the surface. Though not mentioned, the squad is able to recover a single file located off track, which will count up with the final grading.

Mission Update 2
At the surface, the squad encounters the final forces that they will have to take out before destroying the anti air-craft guns to finish up the operation. Pilot ACE is then dispatched to board the operatives in exfil.

Trivia

 * The surface had many changes after release in order to make the end of the operation not so boring and frustrating as some players experienced.
 * The surface was expanded in size, adding in a new area with tents and containers to crowd it with more CI.
 * Barricades were added in front of the elevator, which avoids the issue of the O5 walking straight into gunfire and only having the elevator as cover.
 * The amount of AA guns were changed from 1 to 4, with the 3 AA guns being located in the area next to the helipad.
 * This is the first operation to ever feature weapon customization and perks in the very start of the operation.
 * This is also the first operation to ever include cinematics, only having 2 almost next to each other.
 * This is currently the only operation with satellite imaging relating to the mission.
