Metal Slug is a series of run and gun video games first released on Neo-Geo arcade machines and game consoles created by SNK. The player starts with only a simple handgun, as the game progresses the player may pick up new weapons. The player can only carry and use one weapon at a time, when a new weapon is found it replaces the previous one. Similarly, when ammo runs out, the player reverts to using the handgun, which has unlimited ammo.
Metal Slug gameplay of the series is characteristic of run and gun games: large numbers of enemies and a player character with extremely powerful weapons. In most run and guns, contact with an enemy leads to annihilation. In this series, however, contact results in the opportunity to perform a melee attack and the opportunity for the enemy to perform a melee attack of his own if he has one. The player's melee attack is also much stronger than most shots.
Metal Slug leads to the ability for the player to run in and use melee attacks to take down a number of troops, and the ability to quickly defeat enemies that can take plenty of damage like the mummies in Metal Slug. Collect many interesting weapons and bonuses, fight againts many giant bosses and use many interesting vechicles like tanks or aircrafts.
