Buy Metal Slug 7

Back on the Neo-Geo Pocket Color (for all 5 of you who may have had one), there were a couple of Metal Slug games - First Mission and Second Mission. These games were actually made from the ground up to be handheld titles. There were branching missions (slug-plane gets shot down, go to one mission; make it to the end of the level, go to another, etc.), health and rank upgrades, unlockable characters. It took me about 6-7 playthroughs to see everything they had to offer.

Metal Slug 7 unfortunately is basically another iteration of the arcade series. It's very short, completely linear, and is very little bang for your buck. It's fun while it lasts, but when you get down to it it's like a prettier, funnier, easier Contra, one that you won't want to replay nearly as much.Get more detail about Metal Slug 7.
