Re: Flash Games
Very fast and short guide for baloon def:
Tag shooters up to 3, always upgrade to blade shooter before range and upgrade to full tech before buying next.
Before level 20 you need to invest to one cannon. Make it to target always last always upgrade to best scraps (or what ever sharpnelss or so) NEVER upgrade to missiles!! Missilies sucks misses much much more than normal shots! and make it to fire at the very beginning (You use these to pop all immune to sharp balloons, not to really make damage).
After that point you buy 3-6 more tag shooters and upgrade those, and then invest to 1-2 more cannons.
Then save until you can buy super monkey (you must get super moneky on level 30 or 3x before ballon ships), next upgrade it to laser and in case you miss something just spike trap it. Then you can wait and invest to another super monkey pretty easily before last 3-5 levels and possibly upgrade that to laser too.
I have finished all first 4 levels on hard with this concept. Tags (blade shooters) are best mass killers in game, when you put those to very close packs of 2-3 units to close areas you can blow basicly anything before they get even near of getting out of range.
