Metal Slug Revolution is a new game based on SNK Playmore series for iOS and Android.
Marco, Tarma, Eri, and Fio from previous releases are in the game, which is a bit different from the side scrolling shooters released before as the gameplay looks to be similar to an action RPG. The Slugs in this game will follow you around & there are 250 different types of Slugs in the game with over 150 stages based on levels from the main Metal Slug titles to play. There's also player vs. player multiplayer too and a Survival based co-op mode that sees you fighting bosses with friends. No word just yet on a release, but there is a Korean trailer you can see below:
