(You can only do this in the last age) first build up your turrets, the iron cannon is 
the best, then just wait till they send troops over and dont build anything you will 
get alot of money then keep using the special ability (the big laser) and wait till 
you have about 25,000 gold/money and build 2 gods wrath and then build about 2-5 soldiers 
with the laser on their hand (the first one) and use your big laser to get rid off their 
soldiers and u will win, I did this and won.
