Metal Slug 4 (NGM-2630) — About this game

Metal Slug 4 (NGM-2630) adds a timed scoring opportunity to its running, shooting and vehicle combat. Collecting a shield-shaped emblem starts the Metalish system’s timer, rewarding a sequence of enemy defeats within its allowance. Nadia and Trevor join Marco and Fio in the campaign against the Amadeus organization, with the Dual Machine Gun adding another weapon option. Rescue and movement decisions still matter during a scoring attempt: an emblem is most useful when the route ahead can be cleared safely, rather than when collecting it forces the soldier into an enemy’s attack.
