The Marker takes 250 balls of that Gun (the 2nd worst gun, 1st is machine gun, than that one with green things). When a ball hits the wall, colour was turned into orange and is way smaller... So basically its that gun with other skin, more damage (almost instant gib) and faster!
As soon as we got 2 more maps edited we can play this... Also I need the package New, can anyone send me?
