As you work through the scenarios, more units become available. You begin with a certain amount of gold and must purchase units. There is also a limit to the number of units you may have, which is tied to any upgrades you make and also the experience points you have gained. So, in the beginning, you are only able to have two or three units, and with each success the number increases. There is a point system which is connected to how many units you select for the war party and upgrades.
Units are either of the guard or range type.
Starting the game our helping guide tells us what to do this scenario. The building textures need a bit of help. On the right, we chat with a shopkeeper. You can upgrade these three categories either in the game at the shops or in the war party editor. You can upgrade any category you like in any order, as long as you have enough of the experience points, gold, and control points mentioned previously.
