Gameplay
The Lost Frontier is filled with trademark Jak and Daxter gameplay. In the form of either Jak or Daxter players engage in a combination of mandatory and optional missions where according to the level played, they will face action or puzzle centric situations, and in some cases a combination of the two. Levels played as Jak lean more towards action gameplay, with players engaging in combat in the air and on the ground as they platform, and wielding a customizable gunstaff, Jak's weapon of choice. Levels featuring Daxter require more puzzle-solving skills. In both though, players must utilize the power of Ecos, the same elemental substances found throughout the game series. Categorized by color, Eco is responsible for and used to enhance a variety things, including life, motion, strength, power. In addition, the mysterious dark and light Eco are extremely important due to their ability to be used as the basis for hidden character-specific moves, power, weapons and technologies.
