To find the scavenger hunt winter project hidden stash in the Division 2, where the text says “One of the control points in the western part of the city” and “Party like the end of the world”. The Location for World’s End Control Point is in Downtown West, you will find the stash inside the Supply room, on the left side of the crate. You will get the Festive Delivery Backpack (see the last image below).
Take a look at all the winter project locations here.
The complete text for the winter project is:
