"Grab the nearest heavy machine gun because SNK Playmore just released Metal Slug X for Steam. This run and gun game is a remix of Metal Slug 2 with six levels in arcade mode. Players will still see the Camel Slug in the first stage, which was the start of more wacky "vehicles" like the electric shooting Elephant Slug and Ostrich Slug found in Metal Slug 3.
Metal Slug X for Steam has achievements, leaderboards, and online co-op multiplayer.
Metal Slug X costs $7.99 on Steam. A two pack is $12.99."
