Hello everyone,
The videos for the bottles and the seagulls locations are great, but one thing bothered me: it's two separate videos. That's a bit annoying to have to switch from one tab to another, back and forth, and to don't know the chronology order where we have to meet those points of interest.
So I found on YouTube a video gathering both achievements, and you can follow it while doing the story of the game, without wondering if I missed something or switching between two tabs.
