Metal Slug (メタルスラッグ Metaru Suragg) is a run and gun video game developed by Nazca Corporation and published by SNK. It was originally released in 1996 for the Neo-Geo MVS arcade platform. The game is widely known for its sense of humor, fluid hand-drawn animation, and fast paced two-player action. It is the first title in the Metal Slug series. It has been ported to the Neo Geo CD, PlayStation, Sega Saturn, Virtual Console, PlayStation 3, iOS and Neo Geo X, and to the Wii, PlayStation Portable and PlayStation 2 (as part of the Metal Slug Anthology).
Gameplay is very basic; the player(s) must shoot constantly at a continual stream of enemies in order to reach the end of each level. At this point, the player confronts a boss, who is usually considerably larger and tougher than regular enemies. On the way through each level, the player can find numerous weapon upgrades and "Metal Slug" tanks. The tank is known as the SV-001 ("SV" stands for Super Vehicle), which not only increases the player's offense, but considerably adds to their defense.
