i belive there should be mountable machien gun for defence for things like fortresses, bunckers, and trenches. they should have a clip of 100-150 bullets and each hit dose about 20-25 damge (so its not to over powering) each player can only get 1 from thier base and can not get another one until the machine gun is destroied (can eb destroied by destroying the block under it) if you get trigger happy be warned! the gun will over heat and wont cool down until 20-40 seconds later so be advised. to tell when the gun is going to be overheated i belive there should be an icon of the gun in the lower right corner of the screen above the ammo and it fills with red until th whole gun becomes red = Overheated. just to tips if this actually comes out the make sure the hole or what ever you firing out if is small (machien guns are the 1 targeted defence)
