Vikingland

The Viking country for a long time there were no wars, brave warriors relaxed and resting in a tavern. Suddenly a monster appears in the doorway and declares war on the state. His, of course, throw off a cliff, but begin to prepare for the attack. Build an impenetrable barrier of shooting towers upon receipt of trophy assets, do not let the evil ugly monsters seep through your cordons, transform the way of life in the path of death.
