Crackdown was that rare treat, a game bundled with a goodie everyone wanted, in this case access to Halo 3 Beta, that actually turned out to be really good as well.
While everyone was following over themselves to make GTA clones the man originally behind GTA went of and made a sandbox game where you played super powered cop, out using some excessive force against the local paramilitary criminals running your fair city.
Crackdown 2 looks to have a few new surprises in store.
As you can see from the trailer above you still play a super powered cop out tearing up the streets, leaping buildings in a single bound and dropping on criminals like some combination of Batman and the Punisher. But there's something new to be concerned about, some big genetically modified beasties by the look of things.
(side note: I keep reading about a zombie theme to this game due to the "The city is infected, you are the cure line", I'm pretty sure they mean the city is infected with crime. As for the monster moment faithful Crackdown players will remember the genetically modified monsters that roamed the streets towards the end of the first game, safe bet these monsters lead on from them. Personally, if I was at E3 I would have checked up on that before writing made up stuff, I'm not bitter I'm just saying... okay maybe I am bitter).
