ok a trick to beat the story mode 3 missle launchers all upgraded all the way then 22 gunmen and 22 repair men and your wall level 5 and your gun the mashinggun the 1 that costs 11000 dollors upgraded all the way and u win the game
it would be cool if u could put like turrents or towers on the top of the base and why dont they attack from the back or the sides why they go to the frount (SIR WE WILL KEEP DIEING AND GIVEING HIM MONEY)
