Gameplay

Metal Slug 1st Mission plays similarly to other Metal Slug games, but has toned down graphics for the Neo Geo Pocket Color hardware.^[3] Notably, grenades are thrown by pressing the option button to switch, then fire. This was changed in the sequel. When the game is completed once, another character becomes playable. There are five different difficulty levels: kids, easy, normal, hard, and very hard.
