Metal Slug's popularity can be attributed to its accessibility and charming visuals, which most mobile users can now experience. The original Metal Slug is now available for Android devices running Android 2.3 above and iOS devices with iOS 4.0 and above. Thanks to fan demand, Metal Slug 2 and Metal Slug X are scheduled to follow.
Not only is Metal Slug being touted as an "arcade perfect" port, but it also features Bluetooth multiplayer and online rankings, so you can battle your friends in more ways than one. The game is available in the Google Play and Apple app stores for $3.99.
