Finished 100% all all levels.  I think I saw notification that game completion was 99.7% complete, after the last survival cache was collected.  Is there any way to get 100%. What did I miss? Feel kind of deflated now it is over.

Hey, Donna. The most commonly missed items are challenges and collectibles in Cozumel, since that area of the map is separate from the main map. I also have a few other suggestions and a checklist here: https://tombraiders.net/stella/walks/TR11walk/100-percent.html

Hopefully that will help, but if you still can't figure it out come back and we'll look into it further. Good luck!

Thanks will have a look.
