Karate Kid pose
Stand directly in front the fireplace at the Lara's home. Press [5] + [Up] + [4]. Hold [4], but release in mid-jump as you come down. Laura will do the famous Karate Kid pose with her arms stretched out, standing on one foot.
Sexy climb-up vault
When lifting yourself up onto something, you can do a little vault up. Jump and press [4] to grab the edge of a platform. While holding [4] to hang there, hold [Up] + [7].
Swan dive
Stand at the edge of a platform or similar location. Hold [Walk] and [Jump] + [Forward]. Lara will do a swan dive that will save you from the horrible screaming that results when you do the normal jump from a high place. Note: If you use the swan dive, you will die even if its only two square spaces in height because Lara lands on her head.
