Ratchet & Clank Future: Tools of Destruction - PS3/Quick Strategies

From WikiCheats

For the Love of God, Turn Off SIXAXIS

Turning off SIXAXIS is highly recommended. Flying, free falling, and even the Decryptor sequences are all much much more responsive, and therefore a much more fun, using the analogue sticks. Fact. The only thing that does not work without SIXAXIS is the Tornado Launcher which, incidentally, is the worst weapon in the game anyway.

NanoSwarmers

These are the most important weapon in the game when taking heavy fire. Prioritize this to be leveled up first, because it makes the game a whole lot easier.
