The Forklift is a vehicle used in Metal Slug 4.
The name says everything, this vehicle doesn't have anything that can be considered as 'weapons'. You can shoot with your gun that you have at the moment. Take care of enemy fire because this vehicle can't protect you from shots from above or behind. When you press the "grenade" button this vehicle can hit enemies with its front fork(Like in picture). It uses up its' own grenade 'ammo', which is ten, and instantly kills anything with it. When you press the "jump" button this slug will jack up like the Drill Slug. If you want return to the floor press "jump" again. This can be used to avoid any fire, as the vehicle itself cannot be harmed.
This slug is only available for the 5th mission in Metal Slug 4.
