Or you could get the addon in the form of an SD card. It costs around £29.99 and was released just over a week ago. It works pretty well and involves wandering aimlessly while the addon plays itself, making it impossible to get lost. Then when you get all 8 certificates of power you fight four strong guys at the end who bend over and let you kick the shit out of them because in fact they are the weakest four guys at the end of the addon ever made.
While the addon in fact is a sequel to the previous addon of the generation, the overall content is different, which is fun for shits and giggles but displays no actual challenge of game play. Hard mode can be unlocked, but I think I'll have to do every fucking thing ever invented in the addon first, which possibly involves trapping a small yellow electric mouse in a room giving it acid and recording results. Questionable actions should not be too surprising in this addon, since it's perception of reality, space, time and underwater tunnels look like they were invented by Boris Johnson tripping balls on ketamin.
All in all I'd say the addon is pretty good, bringing about the plethora of opportunities for competitive play, but it's finding unwilling idiots to battle with which is the entire problem, and in fact it's much less easier and time consuming to use the software for battling online at your computer
