Dear,
After a while of playing i think the engineers really should work together.
You CAN select a few engineers at 1 time with is good.
BUT when u let them build something.. its just 1 engineer and the other 2 - 3 - 4 - .... are just standing there.
If u could let them work together you could get ur building up much quicker..
Plz take a look at this..
Thnx..
