daxter adventures takes place after Jak and daxter go through the warp gate

An old man named Osmo offers daxter a job exterminating Metal Bugs. daxter accepts the job, and completes missions while also looking for Jak

The game takes place in the final months of the two-year gap presented in the opening of Jak II, 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 some 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.

When daxter tries to stop Kaeden from escaping the shop, Kaeden suddenly blows up the shop with a bomb he placed in the shop earlier. daxter and Osmo survive, and daxter promises to stop Kaeden, but only after he rescues Jak.

daxter adventures infiltrates the Fortress and finds Kaeden, who reveals himself to be a giant Metal Bug. daxter manages to defeat Kaeden, who tries to warn him that Kor is waiting outside for them, and then uses a hover platform to begin searching for Jak within the Fortress, leading into the opening cutscene from Jak II. After this, the game cuts to a point later in the timeline at daxter's Naughty Ottsel Bar, where he is recounting the story to Jak, Keira, Samos, Tess, and Taryn.

Gameplay

Due to his new job, daxter is now equipped with an electronic blue eco powered bug-swatter, which acts as his melee weapon, and an extermination tank, which sprays green eco based bug spray to stun enemies.

The tank eventually receives several modifications, including doubling as a type of jet-pack that allows daxter to fly, flamethrower capabilities, and an ultrasonic attachment.

The flamethrower modification allows daxter to hover higher and longer in jet-pack mode. With the ultra-sonic attachment, daxter can shoot a blue eco projectile that causes high radial damage,

but uses one fifth of the player's maximum bug spray. When the player finds a small space where daxter's normal stance cannot squeeze through, the player simply presses the triangle button for daxter to crouch.

The game also features levels where daxter navigates vehicles to move around massive areas quickly. The player can also double-jump in order to reach great heights.

The player can also climb certain areas by using daxter's Ottsel abilities. daxter can also ride on a zipline, jump onto a trampoline to reach great heights, jump from netting to netting and enter portals to other areas.

There are also the traditional Precursor Orb collectibles (1001 in number), which unlock videos about the game.

The game also has a new collectible known as the Golden Bug-Gems, which can be acquired immediately when you kill a bug, excluding the bosses and Haven City termites.

His health can be regenerated by receiving green eco health packs, and the extermination tank's green eco based bug spray can also be regenerated by absorbing green eco clusters.
