Level Select & Test Stages

Metal Slug 4 offers a whopping no unused areas or warps. Bummer. On the bright side, warping straight to the bad ending has an amusing twist.

Metal Slug 4 lacks proper test stages, but instead it's just artwork that cheat sites say you unlock by completing the game, but it never worked for me. Choosing an option that isn't numbered and has a hostage icon freezes the game.

FOR 1
The first one here is a picture of Marco, radioing for help or something. The theme to Mission 3 plays in the background.

FOR 2
This one is of Trevor, pulling some fancy aerobatics whilst some soldier (who looks like someone straight out of an Asterix book) stares in horror. The theme to Mission 2 plays here.

FOR 3
Fio examines her gun in this image, and thanks to the theme to Mission 4 playing in the background, it sounds like something frightening is going to happen, like an alien bursting out of her stomach, some screenshot from The Exorcist popping up, or finding out that she’s actually a man.

FOR 4
Nadia adjusts her hair band thing, and the theme to Mission 5 plays here.
