The Deplanetizer is upgraded from a bare-bones super laser weapon into a downright massive space station.Captain Qwark is less of a coward this time around, even willing to fight Ratchet personally on foot.It helps that he's voiced by Sylvester Stallone in the movie. Here, he is given a very intimidating redesign and some impressive weaponry. In the original game, Victor Von Ion (the robot lieutenant on Eudora) was an unnamed and unimposing coward who hightailed it at the first sign of Ratchet.
He is also more agile than the PS2 game counterpart, and can easily evade enemy shots by strafing. Not only has he encountered more battles, he is also able to stand toe to toe against the former veteran ranger Captain Qwark and win. In particular, Ratchet from the game shows some combat experience, while the film version showed great difficulty wielding weapons before joining the Rangers.
The game greatly expands upon each act of the movie, which is where all of the returning levels from the first game that weren't in the movie make their appearance.
In addition there are new Clank gameplay segments, and some planets have been completely overhauled in design and length, such as Gaspar having a brand new mining sandbox with a jetpack. Some of the weapons from the original game return, along with some new ones, including from the sequels.
As well, Ratchet is no longer in it just to have a good time, but now aspires to be a hero, just like in the PS3 games. Ratchet is shaken by his failure to stop the Deplanetizer from destroying Novalis instead of getting obsessed with revenge, along with the fact that several planets from the original game were removed, including ones that contained major plot points in the original game. For instance, Ratchet doesn't have the nasty falling out with Clank like in the original, due to the event that caused it (Qwark backstabbing Ratchet and revealing he sided with Drek) happening much later.
The characters' personalities and chemistry are also revised to more closely resemble later series entries.Significant portions of the second and third acts have been removed as well, excising fondly-remembered levels like Gemlik Base and Oltanis. Some plot points are removed or simplified for example, Ratchet and Clank find Qwark early on instead of spending a big chunk of the game searching for him.The original video game, due to the plot being an adaptation of the movie's:.Adaptation Distillation: The basic Narrative Beats are still intact, but there are a lot of changes made to the overall progression.
Achievement System: Trophies serve as rewards in this game, with the original Skill Point system being removed.
