Daxter

Players assume the role of Daxter in his role as a bug exterminator, while he is searching for his friend Jak throughout the game's story. Daxter can perform double jumping and ledge grabbing, can crouch to squeeze through narrow gaps, make use of trampolines to reach higher ledges and ride on ziplines, and make use of vehicles to move around the game's semi-open world. The world is seamless with little to no loading screens. Portals and gateways are encountered within the main environment which lead to locations containing missions that players must complete in order to advance the story.

Combat in the game focuses mainly on melee attacks using an electronic blue eco powered bug-swatter, with players able to perform combo attacks on multiple enemies. After the initial missions, the player gains access to an extermination tank which sprays green eco-based bug spray to stun enemies, with it later able to be upgraded with several new functions, including a jet pack to allow Daxter to fly, a flamethrower modification which can improve the effectiveness of the jet pack, and an ultrasonic attachment that shoots blue eco-based high radial damage projectiles. Damage taken from enemies and certain environmental hazards can be recovered by collecting green eco health packs, while the spray tank's supply can be regenerated by absorbing green eco clusters.

The game takes place in the final months of the two-year gap presented in the opening of Jak II (and the aftermath of The Precursor Legacy), between the moment when Jak is taken prisoner by the Krimzon Guard and the time in which Daxter finally rescues him from the Krimzon Guard Fortress. The introduction shows Jak being captured, while Daxter manages to escape. Almost two years later (having no luck with rescuing Jak), Daxter has forgotten all about finding his friend. An old man named Osmo, whom Daxter meets, hires Daxter as an exterminator working in various parts of Haven City, and occasionally its environs, to exterminate bug-like Metal Heads referred to in-game as 'Metal Bugs'. During his adventures, Daxter meets a mysterious woman named Taryn who, despite being less than impressed by Daxter's interest in her, occasionally helps him.

After completing a number of missions for Osmo, Daxter sees Jak in a Prison Zoomer and attempts to chase after it. After being cornered by Krimzon Guards (who had noticed Daxter's pursuit), Daxter is rescued by Osmo's son Ximon, who assists him with several more missions including one to Baron Praxis' palace where Daxter steals a map of the Fortress, the prison where Jak is being held. After returning to the extermination shop, an arthropod sidekick that Daxter acquired earlier is killed by Kaeden, a bitter man who seemingly wants to steal Osmo's shop, but, in actuality, is working for Kor, the Metal Head leader.

Daxter received "generally favorable" reviews from critics, according to review aggregator website Metacritic.
