You can click on the description bar (on youtube(just click video twice) and it will show you the collectibles divided into 5 sections
Act 1, 2, 3, 4, 5
the title of the collectible will be listed with a time marker you can click on to see exactly where it is located. AND All collectibles are in the order they are found throughout the story progression!!!
Just wanted to share this, hope it helps you all out.
