Tomb Raider: Legend

There's basically a bullet point list you need to run down whenever you enter a new area:
1.Watch out for traps that could spring as you initially enter
2.Survey the area for enemies that need to be snuffed
3.Identify what objects you can interact with
4.Devise a method of using the interactables to get to the next room or area
5.Climb your ass around until you get out
