I just have some tips on beating the WMI(particularly the bounus wave). And yes, I know that I should put this on the page, but anyway, here goes:
1. Fill your bunkers with Eye-ras.
2. Put all useless buildings and resource buildings outside to delay the monsters.
3. Make sure the ADT,TH and silo is protected.
4. If possible, use a fast computer.
5. If you failed or the monsters are almost destroying your entire base, press F5.
Hope this helps!
