TIP: This is how I beated this game: Try to get the damage upgrade until you unlock "gun cannon". Then get to a corner, locate your crossair close to the peacekeeper's trench, and keep on firing short bursts. This will spread your bullets from early on, and you should be able to hit all enemies even before the properly appear on stage. If a guy with a shield appears, pop him up with a grenade. All the best, solidarity fom São José dos Campos, Brazil!
I won this game only with "Hood The Habbit". Invest a lot on food creation, auras and voilá, their "go through anything" arrows guarantee a victory as they can be made in HUGE hordes...
It has been quite easy with the chinese. Just get agility, support and attack (passive skills), sit back and enjoy watching the enemy having to deal with hordes and hordes of enemies at a time. I didn`t even bother with towers or enemy spells, just attacked the weakest locations first and soon the map was all mine. =]
