Metal Slug Advance

Metal Slug makes its Game Boy Advance debut as a five-level platform shooter with a number of new twists to the long-running series. While the basic premise is the same as in previous installments (players assume the role of an elite commando sent to wipe out a terrorist army), Metal Slug Advance features a special mode in which players must rescue hostages as well as a play mechanic that involves collecting more than 100 cards. Each card, when found, grants characters new abilities or weapons such as a shotgun, sword, or hyper cannon. The game also includes a number of bonuses to be unlocked by achieving top performances in each branching mission. ~ Scott Alan Marriott, All Game Guide
