I used two fully upgraded flame joes on the outside. Fully upgraded quake box in middle.. Then i fortified all i could, and used the rest on repair men.. i went to go watch LOST, came back, and i win..
you have to get 3000km before it goes in.. my ball went around the map twice and mystically went in at 3490km.. but yea.. it has to be 3000 before it hits.
