One of the game's key elements is the use of gadgets and weapons. As you progress through the game, you will be able to upgrade Clank into a variety of different machines in order to unlock new game areas, or weapons to take on certain baddies. While the demo only showed a glimpse of some of the weapons, it's safe to say that Insomniac is pulling out all of the stops in this one. For example, one of my favorite weapons is the Doom Glove, which allows Ratchet to throw dozens of tiny little robots to attack enemies.
Look for Ratchet and Clank this November, only on the PS2.
