Metal Slug 8 is the newest installent in the Metal Slug franchise, and is published by Aksys Games and developed by SNK Playmore. It is the first in the series to feature newly-designed graphics and character animations reminiscent from King of Fighters XIII. All main illustrations are drawn by Eisuke Ogura. Gameplay mechanics from the third game have slightly returned, but with improved modifications such as more futuristic level designs, the ability to switch out bombs (in Metal Slug 6, you could wield two different firearms and switch them out whenever you felt like it; therefore, this feature works pretty similar), and a "Free Roam" mode where you just complete levels not part of the standard "Mission" mode. New enemies have debuted in the game, with some returning favorites. Music on the game is now done by Yuki Iwai and Tate Norio.
