Lara Croft and the Guardian of Light

This can only be achieved in Local/Online Co-Op mode. Player 1 MUST be using Totec. Hold to raise your shield in front of you and face any projectile throwing enemy. The shield will reflect the projectile back towards the direction you’re facing. The projectile has to hit the actual originator for the trophy to register. The earliest opportunity to achieve this is in the Level 2: Temple Grounds against a bunch of Demons that appear early in the stage and throw Light Spheres. Easily done by yourself, controller 2 doesn't need to do anything
