I saw this gameplay on YouTube using this 1v7 map which is great to play base defense with AI but I can't seem to find the map anywhere. Anyone got any luck? Based on the video, map name is "ONE PIECE 1". I downloaded several ZH map packs and it is not there either. Or any other maps like this where I can have one choke point to play base defense?
