The first three games of the "Jak" series; "Precursor Legacy", "Jak II", and "Jak 3"; are still mainly about platforming. The player controls the character Jak or the character Daxter in jumping puzzles to get to a goal. The character can only get hit by wild animals or monsters only a few times before dying and having to start the goal over, but the character can get life back by touching Green Eco. In "Jak 3", the player can get armor that lets Jak be hit more before dying.
