Chris Buffa (Modojo): Gun-toting camels, fighter jets and mummies. Those are but a few highlights to Metal Slug 2, a near perfect port of the original NeoGeo classic. Released for both iOS and Android, SNK Playmore's intense shoot-em-up has action to spare, as players select one of four characters and lay waste to a variety of evildoers (even nefarious Martians) using a handful of powerful weapons, such as the Heavy Machine Gun, Laser Shot and Flame Bottles. They'll even get to hop onto and inside vehicles. The aforementioned camel, for starters, but also a bipedal tank called the Slugnoid. Does the game look dated? Absolutely, and that only adds to its retro charm.
