Hot on the heels of the release Metal Slug 2 for iOS and Android, Metal Slug X is getting the touch treatment.

Retro-gamers, arcade fans, and new players alike can now enjoy fighting thinly veiled Nazis, Martians, and giant robots on their favorite mobile device, this time without using a small fortune in quarters.

The triumph of gorgeous sprite animation uses bluetooth to allow players to run-and-gun with their friends, and online leaderboards.

Metal Slug X is available on the iTunes store and Google Play for around 16 quarters (3.99).
