The last level entitled Resonance is challenging. It isn't technically challenging though, it's original Tomb Raider challenging, which means you will have to explore carefully, use your eyes and remember where things are. These days folks rush too fast and look for 'new' things, but I'm way past that, that stuff is behind me. Take your time, everything is hidden in plain sight, and if you look you can see all the switches and keyholes from different parts of the level. If you get stuck, don't come to me, go around the area again and look everywhere.
