One of the biggest features Crystal Dynamics used to upgrade the graphics was TressFX, an engine specialized in rendering hair and fur, giving Lara’s hair realistic movement, even with a slight shiver. The game presents one obstacle after another for the player to work through, with each weapons upgrade evolving Lara into the deadly force as she is known to be. The 2013 reboot of Tomb Raider revived the franchise, taking a sharp turn from the dual-wielding master fighter Lara Croft and stripped her down to a young woman focused on saving her friends from a dark mystic force. The updated graphics in the 2013 Tomb Raider game led the way for its sequels to continue to do the same, as shown by Betafix.
