The section of the game that I was able to play, takes part at the beginning of the game, Lara and Jonah, are sitting in a little café in South America, chasing down leads for Trinity, the big bad from the first two games. After overhearing a conversation, Lara sets out to follow, the game skipped ahead at this point, but eventually Lara came to the location of the games first tomb and began to raid it. Something one of the developers pointed out, was that in this game, most of the tombs Lara enters are underground, so a lot of the dangers will come from that, the ones in the first two games were either in caves or off temples, meaning it was more about puzzles than anything else.
After the puzzle, I was able to get into the room that I needed to be in, sadly though, this is where the story for Lara takes a turn, as she removes an item, hoping to keep it from Trinity, but instead begins to cause a lot of problems for the people who live nearby. If you have seen the trailer, you will have no doubt seen the flood sequence that happens, playing through this was tricky, only because the game was pushing me past certain points, is if it had something to hide, in the end though, Lara finally caught up with Jonah and the two butted heads for the first time.
