I can give you a brief overview. On February 3rd, why that date I don't know, they are planning on killing Muaaz and using him for plot. If they succeed, they could very well end the Cubing Ducks. When you get there you will need to kill the fake Muaaz (FMC). That's why I'm sending you to a weapon bunker. After you kill him you need to find the real Muaaz.
