SNK’s series of Metal Slug has been a fan favorite for more than 10 years, and since the company just announced that they will be coming out with a new game, the series is showing no sign of stopping anytime soon.

This latest game is titled Metal Slug XX will feature seven stages, alternate paths, over 70 types of mini-games in the Combat School mode, additional characters, and 2-player co-op via the Ad Hoc mode. The game will be using a 4:3 aspect ratio.

Metal Slug XX is slated for a December 23 release (and we hope sooner) in Japan. Unfortunately, there is no word yet on whether or not it will be brought to Western shores. And kidding aside, those who will pre-order the game will get a free underwear. The debut trailer featured here is translated by PSPHyper, by the way.
