Crackdown on crime, with 3 other friends.
Crackdown came out for the Xbox 360 back in Febuary of last year. I enjoyed the game but also got bored with it after awhile. Playing in a huge city, where you could do anything you wanted, kind of grew old on me after awhile. But I also didn’t play alot of co-op so that might have helped. I only bought the game so I could play in the Halo 3 beta anyway.
Crackdown 2 was announced at E3 and you will play as these superpowered esq policeman who try to stop the crime waves in their city. If that wasn’t enough to announce a sequel, it’s also became apparent that the game will now support 4 player co-op. That sounds pretty cool to me, it actually makes me consider buying this when it comes out. Playing with 3 other friends as you fight crime, or just make the city your exploding playground. But wait, there’s more! It was also announced that the game will now support 16 player multiplayer. 16 people fighting for points, killing each other, making the city a race course in a Deathrace fasion, or just destroying as much as they can all together. It sounds killer and with all the multiplayer Crackdown will hold, I’ll definetly be waiting on this, rent or buy, I’m playing it.
