Metal Slug 4: Mission 1: Let's Rush Through! (All Routes Shown)

Metal Slug 4 follows the aftermath of a massive Martian invasion, with General Morden attempting world conquest again. Only Marco Rossi and Fio Germi are sent to the frontlines, joined by new recruits Tracey Spacey and Nadia Cassel, while Tarma Roving and Eri Kasamoto are sidelined. The playthrough uses Nadia, who wields a taser melee attack. The mission starts in a city, where you collect white or blue emblems to build a Metalish Combo Meter, earning medals at the end. New weapons include the Two Machine Guns. The level offers multiple routes: 2:22–5:04 Under the Bridge, 5:05–8:14 Over the Bridge (leading to the boss). The first boss is the massive blimp Brave Guerrier, which must be destroyed in three sections. After defeating it, Eri and Tarma drive you to Mission 2.
