It seems I spoke too soon regarding the lack of a Crackdown MMO! APB is Realtime Worlds' action MMO, and judging from the awesome character concept artwork, it's going to have a lot in common with Crackdown. And I'm interested because in at least one way it's going to feature something I wrote about: criminals vs. law enforcement.
More to get interested in: 'The game itself centers on player vs player combat and will be the first massively multiplayer online title where player skill determines character progression as opposed to the traditional model of time investment." That's a tall order, and one I'm keenly interested in seeing how it's going to be implemented. That aside, the art direction on this game is gorgeous -- I'm happy to see that the 'good guys' (law enforcement) are just as visually interesting as the 'bad guys' (criminals). Check it: the photo there? That's a cop. Uh huh. The Artwork section of the site has a bunch of great pics; go check 'em out now. It's not gameplay, but it's enough, by gar.
APB is coming out in 2008, according the site, and let's hope this is the hit the Crackdown could've been.
