So this weekend I sat down and finally completed Tomb Raider, and yes I mean "Completed" not "Finished". I found all the documents, relics, and GPS cahces. I also went back and completed all of the challenges. However, I did not unlock three achievements; completing the challenges, finding all the items, and getting 100% completion. Now, this was all don't AFTER completing the story.
I am (kinda) ok with not getting the achievements, but since I have found EVERYTHING and completed all the challenges, I would really like for my completion percentage to be 100%. As of right now it sits at 98%. Even though when I go through all the fast travel locations, they all say 100%. Also some of the galleries didn't unlock. Is that set behind a difficulty wall or is something else going on?
Is this something that HAS to be done prior to completing the story? Is that why the final campfire is called the "Point of No Return"? Has anyone had this happen, or know why it could be. This is on the Xbox 360 version, post patches.
Okay, so I went home at lunch and checked into things. As most everyone was saying, Cliffside Bunker was the culprit. Just like @chaser324 said, there are a couple locations that do NOT have fast travel camps. Once I discovered where I missed the items, I had to travel from another camp to that location.
The problem is that when you have completed the game and want to mop up the rest of the items, more than likely (like me) you are going to scan all the fast travel camps and check percentages. This doesn't work because you will miss some, mainly the Cliffside Bunker.
Side note; Once I found everything I missed, both achievements popped. Also, I had to use a wallkthrough for the final "Previous Inhabitants" challenge. No way in hell would I have found that one on my own. If you've done this, you probably know the one I refer to.
Thanks for the conversation, duders. Always nice to have intelligent feedback on here.
