Also not sure about the last two. I rewatched the trailer and don't see them in there, though.
Edit: I found them. If you want to unlock them in game I can tell you where they are.
Yes, please! Just be sure to write "SPOILERS" and press enter a bunch so people have to click "View rest" to see.

Thanks! After getting soft locked near there I figured it was just a glitchy area and stopped searching there haha. Nice find!
thanks so much for this
