Hidden Sully pictures
When you are prompted to view your journal by pressing Select, keep flipping back to find an entry with four pictures of Sully, which Nate has apparently drawn over and labeled according to his expression.

Defeating Guardians
To easily kill the Guardians you fight later in the game, once you kill one, take the gold crossbow it drops, and use it on the others to kill them much quicker than your normal guns.

Defeating Lazarevic
To defeat Lazarevic, you must lure him near the volatile blue sap throughout the level. When he is within range, shoot the sap to cause it to explode.
