Let's see, what we've got here in this title that is exclusive to the Nintendo DS is an arcade shooter in the true sense of the words. Side-scroller? Check. Insane weaponry? Check. Frantic gameplay? Double-check!
Metal Slug 7 is, if you will, a stereotypical arcade game from the '90s reinvented for your handheld on-the-go enjoyment, and it truly delivers.
Metal Slug 7 will have you working through seven stages, which isn't a lot in terms of number, but the challenging gameplay will likely make it feel longer. Still, it would have been nice to have a few more levels to traverse. At the end of each, you will also be faced with a boss battles that can be relatively challenging as well. After completion of each boss, you will unlock the different missions from the Main Menu, allowing you to revisit each without having to play through all of the previous missions.
Aside from the Main Mission, you can also play through 80 training missions by visiting the Combat School. These bonus missions vary widely in terms of content, but you can expect everything from item collections to freeing prisoners or war (POWs) and speed mission. Unfortunately, these training missions reuse the same levels as those present in the core gameplay. It would have been nice to have a few different areas to play through.
In all of the stages, regardless of modes, you will be able to choose from six different characters. Each of these characters has their own bio, but more importantly, they also have slightly different weapons' attributes. Some characters may be better at rapidly firing, for example, while others may have more powerful shots. Another attribute that generally differs is that some of the characters offer better close-combat abilities and others can more easily take down machinery like helicopters and tanks. In practice, however, it's hard to see much of a difference while playing the game.
