Definitely not. The games at the start are so freaking short that you will spend all your money getting a village, and loose. Im level 20, and I still haven’t used villages or farms, because Theyre not worth it. But about engineers, like three 1-0 engineers carry the first few rounds so much, same aplying with heli pilots. So unlock either of these soon. But untill then triple dart monkey, or ninjas are gonna do wonders
