Atlus and SNK have released a new trailer for The King of Fighters XIII
that shows off some of the tweaks and changes from the arcade version of the game. I'll admit, I'm not a huge fan of the KoF series (mostly sticking to Street Fighter and MvC), so I'm not sure how damage scaling works in the series, but quite a few of the combos in the video can completely take someone out from full health.
Also, as a reminder, if you pre-order the game at a participating retailer (while supplies last), you'll get a 4-CD soundtrack that spans the game's 15 year history, from King of Figherts '94 all the way to the latest installment. That's a pretty nice pre-order gift.
