Metal Slug Anthology

Overview :
If you know Old School, you know Metal Slug. Am I right? Well, if you don't, this is what Metal Slug is : an old school side scrolling shooter game that originally came on arcade machines. Designed by a company known as SNK Playmore, Metal Slug was the game of the arcade era. It supported upto 4 players in co-op multiplayer as well. It became a big hit in arcades quickly after it came into being, in 1996. After 10 years of this initial release of the first ever Metal Slug game, SNK Playmore wanted to celebrate the 10th anniversary. The PSP being an ideal platform for an old school side-scroller, Metal Slug Anthology came into being, as a compilation of all 7 Metal Slug arcade games : Metal Slug, Metal Slug 2, Metal Slug X, Metal Slug 3, Metal Slug 4, Metal Slug 5, and Metal Slug 6.

Story :
I don't think there is one. Even if there is one, I never noticed. All I know is, there are some characters (can't remember their names ) from which you pick one...
