Warhammer: Vermintide 2

I used this short video (10 minutes) guide inkluding a counter and location.
Credits goes to Epistolary Acumen:


And Imo, an amazing Soundtrack

The good news with this achievement is that it can be done on any difficulty level, including Recruit. This will allow you to constantly pause your run to check videos and/or guides.

I used the video below (its got a nice counter at the top left so you can be sure not to miss any bottles). YouTube user NicoPonk does a good job in getting all the bottles within about half an hour, although they do get a bit confused about locations near the end of the video so you'll be walking in a few circles towards the end. Overall though, if you follow the video and play on Recruit, this achievement shouldn't be too much trouble

(Note: the achievement pops when the last bottle is picked up)
