ok so i've finished all but ONE star in all the maps. I have to say. this is a pretty shit game. the cars handleing is HORRENDOUS. virtually impossible to do some of the stars due to the inability to provide even the most basic of handleing. However I finally managed to get all the badges.
0/5 ONLY because of the handleing
needs working on. i built one of the cannon toers upgraded it twice and buggered off for half an hour. came back and it was still killing everything with a few shots
