The Scotsmen continue their romp through America's national parks when they travel to Yellowstone. The local porridge factory has been polluting the waterways, drawing the ire of the Americans. A bloody stand-off is bound to take place here, and Alfredo is determined to have his army of Scotsmen in the thick of it.

The haggis factory is on the upstream side of the map, at the top of a small waterfall. The cliffs make for an excellent defensive position for the player to start from. However, only two of the six oat fields are nearby, so the player will need to move their front-line troops down into the valley to harvest more oats. The enemy approaches from two sides of the map, split in half by a river, so fighting on two fronts will be required.
