As an Expanded Game, Metal Slug XX refines the classic side-scrolling run-and-gun shooter experience, featuring hand-drawn visuals across seven distinct levels. You will run, gun, throw grenades, and pilot vehicles alongside familiar operatives like Marco and Fio. This version enhances replayability with a Combat School mode for objective-based mission runs and includes the character Leona Heidern. A key feature is the local Ad-Hoc co-op multiplayer, allowing two players to tackle the action together.
As an Expanded Game, this version builds upon its predecessor by integrating new mechanics and content into the established formula. A notable addition is the inclusion of the character Leona Heidern, which expands the roster of available playable heroes for players to select.
The single-player structure is enhanced with features designed to encourage replayability and measure player skill. These include a dedicated Combat School mode, which allows players to revisit previously completed missions while attempting to fulfill specific, optional objectives for score optimization. Furthermore, the POW List serves as a metric tracker, detailing how many Prisoners of War were successfully rescued within each stage. Single-player Rankings are also integrated for performance comparison.
A significant enhancement in this revised edition is the implementation of cooperative multiplayer functionality. Players have the option to team up locally via an Ad-Hoc connection to tackle the seven distinct levels together, combining their firepower against the enemy waves.
This edition incorporates supplementary content beyond the base structure of the original game. This includes the aforementioned co-op multiplayer mode and support for downloadable content, providing avenues for expanded play experiences.
This platformer shooter is accessible across several systems, including the Xbox 360, PlayStation 4, PC (Microsoft Windows), PlayStation Vita, and PlayStation Portable.
