By far, the best Ratchet and Clank game there is out there.
User Rating: 10 | Ratchet & Clank 3 (Platinum) PS2
Ratchet and Clank: Up Your Arsenal is the best game in the series to date. It's main plot takes place in the Solana galexy with the classic heroes, Ratchet and Clank, as they go to stop Dr.Nefarious from destroying all organic life in the galexy. It includes weapons of every sort, from missile launchers to bouncing mine launchers to shield activators. There are the classic weapons from its predacessor, Ratchet and Clank: Going Commando, such as the Bouncer and the Lava Gun. Also, everybody's favorite classic super-weapon, the RYNO, makes a comeback and when upgraded to its maximum power, can turn all of the enemies on screen into a pile of ash. There's obviously the experience-gaining technology for the weapons and armor, as featured and introduced in Going Commando. That means that the weapons can be upgraded to have more power and ammo, and the armor can upgrade for more hit points. There's the classical normal and challenge modes, each one with the same exact storyline and missions, only there are bigger and better weapons and enemies in challenge mode. Finally, unlike R. & C.: UYA's predacessors, the game also can be played online, which is, without a doubt, the best part about it overall. As for an overall score, I give the game a 10.0, since it has so many new additions and expansions to cover for the same old, classical feel of the Ratchet and Clank series.
