Out of all the Ratchet and Clank games, this one is the most deliberately designed to be a shooter. It strips away a lot of the open-endedness of the first two for a more linear, streamlined experience that make me yearn for some of the more unique ideas of its predecessors. However, Up Your Arsenal is fun. It feels great to play and its storyline entertains, perhaps even more so than Going Commando. With or without reservations, Up Your Arsenal is a good place to end the original Ratchet and Clank trilogy.
