There are three tutorial missions. However the instruction confirmation could be a little less transparent since you can confirm and send soldiers to the same spot.
In order to build a castle you must first build a "Keep." The towns and castles must be built on separate lands.
The third training mission offers a sort of obstacle course which requires you to use siege weapons to advance through.
The Siege Tower requires four people to move it around. Once mounted on a wall your soldiers will use it like a staircase, nulling the passenger capacity.
The game will occasionally mix it up with an unusual mission for you. This time it's a stealth one; looking for a Monk.
And though you fight to stay alive, Your body starts to shiver, For no mere mortal can resist, The evil of the thriller.
The load screens show you a map of where you are. The gleam on the sword also doubles as the load bar.
The end of the first campaign "rewards" you with a sandbox to build a castle and town in. There are enemies afoot, however.
The second campaign follows the adventures of Svea, the sister of Thorwald and her husband Geoffrey the Calm of England.
In the second campaign you get the same types of building units with minor tweaks in naming etc but with completely new designs.
