*Update* 05.003.2018

ONLY the first time opening, gives you "Recipes". Any other re-open; MainBase: "Broken Gray-Green Gear-Weapon" and Materials, FOB: "Broken Blue Gear-Weapon" and Materials.

"Container Has Washed Up"-Containers are not included. But that's obvius unneccesary.

Disclaimer: When you entering the first time the ruins, there are a lot of blockades. So you only can get 1. and 2nd Container at first, just in another order(2. Container -> 1.Container).
1. Container: Straight after opening first door, turn right.
2. Container: Walk straight further when you open first door, go down the stairs.
3. Container: This One is vis-a-vis from the Room, with the Bomber, you have acces later in the story to this section, because there is a blockade, when you enter first time.

2nd Container: Straight after Datamass, after climbing ladder, jump down on the left side when you turned back, BRING "Sandbag Footholder" with you! ;-) OK why the heck it,s not possible to just get off the ladder at that position?

First Container is in front of building:

For the second Container, walk behind the Villa:

For the 3rd Container, walkthrough the Villa, till balcony:

Tip:
Use Sandbag Footholder or Iron Watchtower, by the swimmingpool or riverr, to skip first half of inside Villa.
