you know launchers there range has to go round the path to destroy creeper. for example if there was a wall creeper on one side and a launcher on the other the launcher range went on the creeper but didn't shoot because its range didn't go round the wall ;so ether make that range red on let the missiles go round!
You can Microrift them or increase their rang with technytes. But makin the range red would be good. Kind of like a collector from CW
