Metal Slug: Awakening

Metal Slug: Awakening brings a pleasant revisitation of the SNK classic to iOS and Android, starting from its iconic action platform formula and gradually adding new elements both in terms of gameplay and structure, so as to deliver a particularly full-bodied campaign, full of different scenarios, characters, weapons and enemies. It's a real shame that the game lacks controller support, but the touch controls work quite well (despite a few stumbles) and a good job has been done on the graphics front too.
