the perfect technique xD, you can get MAX score (no kidding) in any level, first full upgraded obvious, second, at the satr of the level, build a super tower near your "house", then send ALL the waves, the faster the better, so theyre so closed in togheter, there so many, a bomb will hit all of them :P!!, so crush them with bombs, and the killed tanks give you money, you won´t pass final levels with only bombs, so you need to upgrade your super tower to level 4 (not max, only 4) and the rest of the money use it in bombs, que nearly max score on every level (you can beat me just sending the waves earlier than me, or cheating ¬¬)
HOLY CR4P!!!
aajaja xD, if you full upgrade your bombs, and then send ALL the damn waves, you can crush them all at once with small bombs, plus a super tower, so the one that scapes died anyways, i got 1000 points over the expert score this way, keep this comment alive if you fin it useful! (hard to accomplish on last levels)
