Mid-air Turn
From WikiRaider
The Mid-air Turn is a special kind of Jump in the Classic Tomb Raiders introduced in Tomb Raider II.
During any forward or backward Standing Jump, or jump off a slope or ladder, Lara can turn in mid-air when, immediately after pressing jump the player presses Roll while in the air. (Note: You do not necessarily need to press the Roll Button, up+down will also work.)
