There are two hidden moves in Tomb Raider, the Swan Dive and the Handstand.

Swan Dive
This move allows Lara to dive into water more elegantly. If landing on the ground, Lara will do a small roll after landing. Be careful though, it takes less height then a regular jump to instantly kill Lara if she lands on the ground.

To perform the move make sure Lara's guns are holstered then, while holding down Walk, press Jump and Forward at the same time.

If you are using the default controls this means holding down the SHIFT key and then pressing the ALT and UP ARROW keys at the same time.

A swan dive can also be performed while you're running. SInce you're are already holding the UP ARROW key when running you just need to also press the Walk and Jump buttons together to perform the move.



Handstand
This moves makes Lara climb up onto a block and perform a handstand on the edge of the block for a short amount of time.

To perform the move, approach a block that is at least one full block in height. Grab the edge of the block and keeping hanging there by holding down Action. Now also hold down Walk and press Forward.

If you are using the default controls this means hanging on to the edge of a block holding the CONTROL key. Then while also holding the SHIFT key, press the UP ARROW key.

If you want to skip to a particular level or just want to have some fun these cheat codes can help. However, I recommend completing the game first without using them.

All Weapons and Infinite Ammo (Completion reward)
This is a reward for completing the whole game. After completing the final level and after the credits you will be taken back to the title screen. Start a new game straight away without quitting. When you appear in the first level check you inventory and you will have unlocked all weapons and infinite ammo. I suggest saving your game so you can come back to this after you quit.

All Weapons and Lots of Ammo (Cheat code)
While actually in game and controlling Lara, perform the following steps:

• Hold down the walk key (SHIFT key).
  
• Walk one step forwards (UP ARROW key).
  
• Walk one step backwards (DOWN ARROW key).
  
• Release the walk key.
  
• Turn around three times on the spot, either to the left or right (LEFT ARROW key or RIGHT ARROW key).
  
• Do a back flip jump (ALT and DOWN ARROW keys pressed together).

If done correctly, you'll hear the sound effect of Lara taking out her guns but she actually doesn't. Check your inventory and you should now have acquired all weapons and also 83 Shotgun shells, 500 Magnum rounds and 5000 Uzi rounds.

Level Skip (Cheat code)
While actually in game and controlling Lara, perform the following steps:

• Hold down the walk key (SHIFT key).
  
• Walk one step forwards (UP ARROW key).
  
• Walk one step backwards (DOWN ARROW key).
  
• Release the walk key.
  
• Turn around three times on the spot, either to the left or right (LEFT ARROW key or RIGHT ARROW key).
  
• Do a forward jump (ALT and UP ARROW keys pressed together).

If done correctly, the level should end and the level statistics screen will appear.
