There aren't many game series that can trot out almost the exact same formula six times in a row and get away with it, but Insomniac has managed just that with the Ratchet & Clank games. The secret? By keeping things fresh and interesting through always changing the weapons and gadgets to the point where you don't mind that - to all intents and purposes - it's a minor variation on a theme.
Anyone expecting some sort of radical next generation reinvention can think again. Sure, the game engine has been polished up beyond belief, but when it comes down to talking about the actual gameplay it's business as usual for the big eared Lombax and his faithful robot backpack. Just like every Ratchet game since 2002, Tools of Destruction is set across a series of (extremely pretty) intergalactic locations. You land your ship, you wander around, ears flapping, you whack a cluster of dinky looking critters with your wrench, and blast away at the bigger, harder-looking monstrosities that hove into view.
Each and every time you kill these Pixar escapees, they erupt into a sea of twisted metal and bolts (whether they're squishy critters or gigantic mechanised monsters of maximum doom, curiously). You scoop up said scrap metal automagically, and all this chaos and destruction works on benefiting Ratchet on several levels. The more you kill and the more boxes you smash up, the quicker you level the furry fiend up (gaining more hit points every time you do so), the more currency you end up with and the quicker you can augment your weapon's death-dealing abilities.
