High Security Compound - Tomb Raider 3 Remastered (Level 6)

The Tomb Raider I-III Remastered games are finally here! These games are a faithful adaptation of the original trilogy, and their expansion packs.
I'm playing through these without commentary, showing you as much as I can remember and find. I will get all the secrets and I will aim to get all the pick-ups, but there may be a small number that I miss.
