Great game no amazing game. If you want to survive without loosing a single unit (For the In Game achivement) use the english, upgrade the infantery to Tier 2 (When you had won one battle, so you start with 1500 gold) and DONT ever block completely the way to your BlockHouse. That will make them keep going almost without shooting, but really slow when they get to the walls. If they come by 3 different places, leave 3 "roads" open. You will massacre them, without almost any effort. If you think this information is usefull, please keep this thread alive
p.s to bad it's not in 1person or something
