The run-and-gun title Metal Slug 3 has landed on iOS and Android. It features a stage select, co-op play, and online ranking, among other features. It uses virtual buttons, and is now available for $6.99.
The "Mission" mode lets you pick a stage to play, and in the classic "Arcade" mode you can use a branching map system to take different routes each time you play. The co-op play is handled through the bluetooth functionality of each device. And of course, as a Metal Slug game, it offers a wide variety of Slug vehicles to use to lay waste to your hapless enemies.
