MAP11: Security Central (Project Einherjar)

Map11: Security Central is the eleventh map of Project Einherjar, designed by Impie in 2016 and constructed in Doom Builder 2.

Essentials
The building is split into three sections: lobby, office, and lounge. The opening section is the lobby, which houses the yellow door that blocks accesses to the fountain controls. Flipping the switch lowers the blue key on top of the small fountain.

The red and yellow keys are found in the office section with the two large fountain beds. Both keys are guarded by einherjar: one in the armory in the left wing, and one in the hall of records in the east wing. The red key isn't necessary to complete the level.

Once you have the yellow key, go back to the lobby and retrieve the blue key. Several ghosts spawn in when you grab it: kill them and go to the lounge on the other end of the building: here you'll find a heavily populated bar and an elevator bank housing two exits. The normal exit is opened with the blue key; the other requires all three keys and additionally rewards you with a blue armor for the next level, which you'll probably need.

Secrets

 * A tripwire on the winding stairs leading down from the yellow door briefly reveals a switch hidden behind the Valkyrie Guard emblem in the start point. The switch lowers the medical backpack on display by the fountain. You can also grab the backpack by straferunning through the top of the fountain, then jumping.
 * One of the TV screens in the bar has Veidt's face on it: shoot the screen to open her hidden rumpus room filled with goodies. The jacuzzi slowly heals Juno if she sits in it.
 * A desk switch in the armory opens a closet with a hidden Dessler Frag Cannon.
