American Conquest: Fight Back is the successor to American Conquest. The game features eight campaigns set between 1517 and 1804: during the 25 missions the player tackles missions like finding El Dorado with Germany or conquering Alaska with the Russians at the expense of the Haida. There are overall five new nations and 50 new units to play with, in addition to the mentioned Portugal and the Netherlands.
The gameplay is exactly the same as in American Conquest, meaning that the player constructs a base, gathers resources and builds up his army. The fighting morale is very important and can be influenced by either victory, defeat, food supplies or the equipment your units are carrying. Ten new battlefield maps are designed to offer quick combat between two armies.
