Metal Slug 4 - Gameplay

Gameplay

A bonus scoring system was added that allows the player to be rewarded depending on how many enemies are killed in the time allotted. The time allotted is determined from the type of emblem that is picked up. A time meter will appear on the top of the screen, and if the player lives through the end of the level, they will be awarded bonus points for badges that represent feats accomplished. Eri and Tarma were replaced with Nadia and Trevor.
