It all starts with the visuals - which are nothing short of great. The series' trademark style is back and received a nice HD makeover. Everything has a familiar feel while also benefiting from a few extra polygons, sharper texture work and an expanded set of animations. There is always something going on in each level, whether it be hundreds of ships zooming though the skies or little worker robots going about their business (until you whack 'em with the wrench just because you can). All of that is before you begin to delve into Ratchet's arsenal of weaponry and get yourself into some pretty intense fire fights - then the fireworks really kick off. Best of all, everything happens without a single hit to the framerate.
Music is, once again, fantastic. Every level has its own theme that manages to set the tone for that particular area while also blending into the style of past games. All of the dialogue is top-notch and voiced to perfection. Punch lines have perfect timing and, although the game doesn't get as joke heavy as past games, there are still plenty of laughs and if you listen closely, you'll hear (and see) dozens of references to past games. During the prison level you'll hear names of past enemies called out over the intercom, while in another, you'll see cut scenes from past games playing on a series of monitors.
