About Metal Slug 4
Metal Slug 4 is a 2D arcade run-and-gun shooter developed by Mega Enterprise and Noise Factory and published by SNK Playmore in 2002 for the Neo Geo arcade system. It continues the legendary Metal Slug series with more intense action, new enemy factions, and a fresh set of playable characters.
The story follows the Peregrine Falcon Squad as they investigate a new terrorist threat led by the mysterious “Amadeus Syndicate.” As expected from the series, the mission quickly escalates into large-scale battles filled with military forces, advanced weapon systems, and bizarre mechanical enemies.
While keeping the core arcade formula intact, Metal Slug 4 introduces new characters and slightly different visual and gameplay pacing compared to earlier entries. The game maintains the franchise’s signature hand-drawn pixel animation style, chaotic combat flow, and over-the-top explosions that define its arcade identity.
It remains a solid entry for fans of classic run-and-gun arcade shooters, especially those who enjoy cooperative gameplay and fast reaction-based action.
How To Play
In Metal Slug 4, players fight through fast-paced side-scrolling arcade shooting stages filled with enemy soldiers, machines, traps, and heavy boss encounters.
Players can run, jump, crouch, and shoot in multiple directions while pushing forward through tightly packed enemy formations. Grenades are used for heavier damage, especially against armored vehicles and large groups of enemies.
Throughout the game, players can collect different weapons such as machine guns, rocket launchers, shotguns, and flamethrowers. Each weapon changes combat style and helps handle different enemy patterns during missions.
The game also introduces new playable characters, each with slightly different movement feel and combat response. This adds variety to co-op sessions and allows players to adjust their playstyle depending on preference.
Vehicles like the iconic Metal Slug tank return, offering stronger firepower and temporary protection. However, players must still rely on movement and timing, as vehicles can be destroyed under heavy enemy fire.
As stages progress, enemy waves become more aggressive, and bosses require quick reactions, precise dodging, and constant repositioning to survive the arcade pressure.
