Coded Messages Locations

Note: The quest unlocks after finding one of the four coded messages. All coded messages are located in the DeLuxe Bathysphere showroom while completing the quest to make the repairs for Suchong’s machine.

  • Coded Message #1: Found inside the restaurant with a large “Medicine” tarp hanging over the sign. Look on the desk down the hall from the bloody surgery table and the Possess KO Mod.
  • Coded Message #2: Look in the back room of the diner marked with a “Food” tarp. On the desk, next to the safe you’ll find a desk with another coded message.
  • Coded Message #3: In the Bathysphere Service Bay, enter the flooded office beneath the hydraulics switch. Its guarded by two auto-turrets. The message is sitting on the desk inside.
  • Coded Message #4: After Atlas gives his word to provide an Old Man Winter plasmid, return to the Test Drive near the beginning of the area. Knock on the door to Atlas’ little HQ, and enter the back rooms of the Old Man Winter plasmid store to find a desk with the last message.

After finding all four coded messages, return to the Manta Ray Lounge. Go to the far back-left corner, behind the locked door or past the closed elevator to the Executive Suites.

Look for three wine bottles in a display. Interact with all three bottles to unlock Atlas’ hidden lair.

I def found the messages and it said check out the manta ray loung, when i go there i cant interact with the wine bottles. It doesnt give me the option. Could i have glitched this by already going threw the lounge?
