During all the fracas the little girl is kidnapped, leaving behind a device that sees Ratchet and Clank set off, yet again, on another adventure in Ratchet & Clank: Size Matters.

Ratchet and Clank have enjoyed much success on console, but this time round Ratchet & Clank portable for the first time on Sony's PSP. It's a bit of a jump considering its predecessor had an open environment that was enjoyed as it allowed for more exploration of planets. So the question really is "does size matter"?

Well at first, the look of the game is OK and seems to have been kept in line with what most are already familiar with. As you progress, you'll notice that the environments' openness is maintained and has that crazy character look to it. Considering it's on smaller scale, it's actually pretty impressive. You could even ague that it's on par with its predecessor. But some of it is a bit smoke and mirrors as you can only venture so far before falling into the oblivion.

Ratchet starts out again with his trusted wrench, which can be swung or thrown at enemies, and boxes that release collectible nuts/bolts. These can be used to cash in on more arsenal or buying addons. The arsenal too is pretty much what you've seen before, from the air cannon that sucks in enemies to use as ammo, to the standard laser. Your weapons grow with continual use, like an ongoing upgrade, so the more you use them the more effective they become against your enemies.

However it's not all about smash and bash. Some tasks are specifically designed for places where only Clank can go. Although these tasks involve a bit of combat, a large majority of it is puzzle based. Clank roams through small cracks, setting free his mini bots. Tell them to wait or follow or unleash them on approaching enemies and stand back and watch as they carry out the dirty work for you.

Clank's adventures are not just restricted to small cracks in the wall - he also ventures into space as well. For this part of the game Clank is super sized and gets upgraded with space bombs and lasers. As you fly through space you have to avoid large obstacles and rocks and in between all of this, shoot down enemies and destroy mini bosses. This part of the game is pretty good with so much activity going on onscreen, especially when you shoot off Clank's bomb which just explodes like a fireworks display.

Clank's space adventure is great, but short lived - a bit of a shame really, because it builds on Clank a bit more than just being the portable bot. However, there are other mini games throughout for both heroes, which vary from racing to problem solving. It's a great way to break up the game as it moves away from smash and bash and focuses more on skill.

It's not that difficult though; you just need to remember the layout of the controls. For example, the D-pad and analogue nub can be used to move in any direction when the wrench is in use. However when Ratchet has an active weapon, the pad is used to move side to side and the nub becomes your primary way to move around freely. The other thing to contend with is the camera angles. Without the second analogue stick you can't quickly get a view of what's around you, or more importantly what's attacking you. For this you have to use the triggers to swing the camera around. A bit of a pain and cloud have been better to zoom the camera out a bit, so it's not covering enemies from the back.
