Prototype 2: Unlock Insane Mode

In Prototype 2 for the PS3 and Xbox 360, if you’re already a pro at the game and you need something a bit tougher, you can unlock the hardest difficulty in the game which is Insane mode.

To unlock Insane mode, you just need to complete the game on the Hard difficulty.

Don’t come crying to me when Insane mode whips your ass though.. just saying.
