Disclaimer, this will be an extremely truncated version of the full walkthrough by Trainierx. This is for those that just need that super quick run through for a daily streak. For this reason, there won’t be any real progress made on collectibles or the like, this guide is just for the achievement “Legacy” above.
Just follow along with the video linked below, make sure to grab and look at (tilt to the same direction) the same relics as are seen in the video, most if not all are necessary to progress the mission objectives or as tools to complete those objectives.
PS - all the jumping is because it makes Lara move a bit faster than just walking around.
