It's out, it's cool, I may or may not spend money on that, I usually don't play arcade games, especially because it cost's $20.00 to get a $10.00 game, because of the funky amounts you can buy them in.
You cannot jump, you use your hand to grapple, but the interface is not great, you grab with B, Reel again with B, and then pull yourself up with Up, this isn't the same for swinging, it's ridiculous.
But it's fun anyway.

It looks a lot like Duke Nukem Manhattan project...

Anyway, I haven't played it yet but will probably download it when I get on Live later on...Also, yeah Microsoft should sell cheaper versions of the cards. Even if you buy points with a credit card it's not economically if you only want 800 points. They force you to buy at least 1000 points..

what about Fable 2 : Pub Games on live

i've never really got into 2D games where you can't jump, I have no idea why, must be a preference thing.

Yeah, The concept is to fight work with the arm, instead of jumping, I personally have no problem with it, except I never want to spend my Money$ on arcade games, they have not proven to be worth it.
