This is actually a bootleg of the original Metal Slug 3. They just slapped the number 6 in it to make people believe that they're actually playing Metal Slug 6 but its not. In this version, you're character is kinda OP here since you start with a Thunder Cloud item and you turn into fat mode every time you pick up a weapon. You can also destroy any opposition within a sec due to the increased damaged of the weapons for some reason.
