I'm only at lvl 18 and haven't unlocked Falcons yet. What would be the best defence against the golems? I have tried many units such as Colossus, Wasps, Bazookas, Beetle Tanks, S-trikes (d'oh!), and I might try Kamikazes. I've heard Wasps are decent, but I'm not sure since the rest of my turrets, well, since I'm low level, won't have too much of an effect.
