Bout as good as the other two R&C games before it. The Qwark side-scroller levels were fun and an appreciated change of pace. There was a good amount of variety in the weapons on stock in this game, bout as varied as GC. Those zero gravity levels were some of my favorites. I do vividly remember hating Dr. Nefarious though, dude was MAD annoying.
Up Your Arsenal is, perhaps, the defining Ratchet & Clank game. It focuses far more on combat, weapons, and humor then any of the past games while still having enough platforming to spread it out and that’s what makes it better. With multiplayer to deal with and challenge mode being double the fun as the first run was, makes this great game greater.
I really enjoyed it, but a whole star is taken off due to the fact that the enemies aren't as diverse and the levels often feel empty, like this title was rushed compared to the first two. Dr. Nefarious, however, is a great villain, and his goofy antics combined with his relationship with his butler make the cinematics a lot of fun to watch. However, even with similarly great gunplay as Going Commando, this is my least favorite original trilogy game.
Up Your Arsenal has a high level of ambition that simply could not be met within its year long development cycle. What came out was a great playing action game with a poorly developed story and a lack of variety. The characters, cutscenes and combat system are great, but you aren't getting the same level of polish expected from Insomniac.
The ying in my favorite third person shooter ying yang. I like it because it's fun... Yeah. I love the art style, I love the cheesy humor, the shooting is really fun, and the weapon variety is elite. Call me when they make a more fun third person shooter and it'll overtake this, but for now, this is it.
