Ken McKown writes: The Ratchet and Clank series has become one of the most prominent platformers of this generation. When Sony and Insomniac announced that All 4 One would not be a traditional sequel for the series, a lot of people were rightfully unhappy about it. All 4 One is a four player co-op affair that happens to feature your favorite characters.
It is more of an arcade action-style game than a straight up platformer, but it still retains that Ratchet charm. If you can get past your initial concerns and take it for what it is, All 4 One is definitely one of the better co-op action games I have played in recent memory.
