M1: Black Market Buy (Penthouses)

Upon reaching the penthouse level, you will trigger a stealth tutorial. Energy is free for this tutorial. Mimic the holograms to complete it.

After the stealth tutorial, dispatch the two Jinn guards who were part of it. Sneak north to spot the first guard, wait for him to drop down a ledge, follow him, and take him out.

Turn east to find throwable objects. Toss them north past the second guard to distract him, then take him down.

Continue east to prompt the combat tutorial. Mimic the green holograms to complete it. This tutorial teaches about using the “Typhoon” augmentation and throwing grenades (press [R1] / [RB] to throw, hold [R1] / [RB] to plot trajectory).

Return to the elevated vent before the combat tutorial start and climb in. Follow it east, then north until you find an exit to the west.

Move a nearby Cardboard Box to find a Biocell.

Exit the vent and follow scaffolding north. Stay elevated and east, working your way north until you find a doorway to the east.

Continue east through a blue-tiled stairwell room and into a penthouse. Disable the Jinn guard inside.

Turn north and leap over an unfinished cinderblock wall to reach a ledge overlooking a gas-filled chamber. Use the “Implanted Rebreather” augmentation to drain energy and avoid damage from the gas.

Drop into the gas and crawl into a vent along the wall to the north. Open a vent cover (press the cover button to crouch behind walls or objects) at the end of the vent.

You are now in the eastern end of the Observation Lounge. To the north is some cover. On top of the southern of these “fire resistant panels” you can find a cup.

Wait for the nearest Jinn guard to be looking away, grab the cup, and throw it against the eastern wall to lure him. Circle around the cover and take him down.

Head north-west to find a ladder onto some scaffolding. Go west through a decorative hole in the wall to dispatch another stationary Jinn guard.

Head north, then east along the scaffolding to find another vent to the north. Continue through this vent and ignore the fork to the north.

Bust through a destructible vent to the east. Continue east past the destroyed vent and find a vent cover to the north leading into another penthouse.

Two guards are in this room with the signal booster. Wait for both guards to be looking west. Activate your Leg Silencers and drop into the room, moving north to find cover.

Deactivate your Leg Silencers. Wait for the mobile guard to patrol to the eastern end of the room. When he turns his back, take him down.

Dispose of the second guard who perpetually faces west.

Deactivate the signal booster to complete the objective. Loot the room, specifically the eBook “Tales of the Arabian Front” on the server case immediately east of the signal booster.
