MBLAQ has returned with their 4th mini-album, and it looks like they're taking no prisoners this time around. The boys have just unleashed the music video for their title track, "It's War", and it's jam-packed with gritty action sequences, high tension, and intense acting from the members. Lee Joon and Thunder were spotlighted in a previous teaser, duking it out over a girl who throws herself in harm's way to protect her lover. Now fans will get to find out the backstory and the result of the fight. Check out their MV below!
