Part 1 ? Well , I couldn't get a solution for Robin Hood's bow and the treasure (Where's the lever !) I like the first one because the were 3 raids (More like minigames) but this one looks like a real tomb raider recreation of the cradle of life (Yes , I watched that movie)
Watch this video and you'll find the way to the bow. https://www.youtube.com/watch?v=0oG7ZVl_VGY. And otherwise the only inspiration I took of Abu Simbel in Egypt. A similarity with Tomb Rider movie is just a coincidence. I look at the movie because I'm not sure that Tomb Rider it is but otherwise it's just a coincidence.
