Metal Slug Run is an action packed online game in which you take the role of the commando who has been sent out on a very challenging mission. The good news is that you are a highly trained commando who has already accomplished various other challenging missions before this. Let us see if you can be successful yet again. You will have to move through the enemy territory very watchfully and attack the enemy units wherever you spot them. Remember that the enemies will also be attacking you and so you should always try to be the first one to attack because as they say attack is the best defense.
