About Metal Slug X
Metal Slug X revisits Metal Slug 2 with altered enemy placements, extra weapons and revised encounters.
Familiar stages, rearranged encounters
X revisits the environments of Metal Slug 2 with rearranged enemies and new weapons. Familiar stretches can lead into a different fight, so recognising the scenery does not tell you exactly what comes next. Vehicles and transformations interrupt the infantry shooting along the way.
Returning from Metal Slug 2
Treat remembered enemy positions from Metal Slug 2 as a starting point. Leave room to react at the edge of the screen: X changes encounters inside those familiar stages.
The games behind X
Compare this revision with Metal Slug 2 to see the earlier campaign layout. The original Metal Slug is a separate set of missions.
Background and mechanics: Wikipedia game reference.
Secret Codes & Cheats
Check the edition and timing requirements before entering a code. Button names refer to the emulated controller; use your assigned keyboard or controller inputs.
Fat Player Super Transformation
