when it comes to tech upg, i suggest maxing out the tech then energy reason being u want to tech out as soon as possible so that u can trade those space wasting technodomes for more mass energy ull end up with +50 energy or more on some lvls happy blasting XD
for an early game strat dont noob it with a bunch of technodomes that will kill u. instead mass reactors for the energy if u dont need any or very little defence. then u can decide on technodomes or defence depending on the mission grab ore and gems when u can those gems can give u a much needed boost XD
alright for anyone getting ran over with creeper heres an aggressive strat: 4 blasters, 2 makers @ x4, and 2 launchers in order from front to back. u can add 2 more makers and/or launchers to suit ur needs. blasters for drones, makers for frontline anti creeping, and launchers for long range mass creep blasting
mages are overly powerful. they never miss (unless target is already dead), 50 max damage, no need to improve marksmanship (upgrades accuracy which is a waste for mages), just improve speed and armor and your good to go. armor upgrade allows them to be hit a couple of times. especially useful when your already at the end. oh and theyre great against mountain trolls.
one turtle bounc4ed around and gave me 3000 hits by itself... should i feel bad for him now??? nah put in more stuff then see what happens MUHAHAAHAHAAAAAA
i've played several td games but this one here is by far the best setup i've ever seen also has an excellent story line as well i only wish there were more missions 4/5
