Metal Slug X is a horizontal scrolling Shooter from SNK
This game is similar to its prequel Metal Slug 2, only better. This explosive shooter is about one thing and one thing alone:
pure firepower. Each stage in METAL SLUG X is stocked with enough enemies to
keep even the greatest of soldiers busy. Start by choosing your character from
four trigger-happy warriors (two male and two female), then set off into
multiple stages of enemy territory with only a handgun and a stash of grenades.
Find more weapons that are powerful, rescue POWs to earn power-ups, and hop into
combat vehicles called slugs to send the bad guys running for cover. Just when
you think you’re through, at the end of each stage you’ll find an enemy boss
just waiting to take you down. One of the Best!
