Metal Slug 7[b] is a run and gun video game developed by SNK Playmore for the Nintendo DS.

The game was released in 2008 for Japan on July 22 and North America on November 28 by Ignition Entertainment.

Several years following the events of Metal Slug 4, 5, and 3D, the Peregrine Falcon Strike Force, the SPARROWS, and the Ikari Warriors are once again on a search for General Morden and his army, this time on a giant island landfill that has been converted into a military fortress, in order to stop his latest coup d'état.

After having his newest weapon crushed by the heroes, Morden receives unexpected help when a time portal opens up and high-tech soldiers from the future appear to pledge their support.

With their advanced technology, Morden is able to further fortify his base, but the heroes push forward despite the incredible odds.
