In Monsters of Loch Lomond, you are the leader of a Scottish clan that is competing with other clans for control over the Loch Lomond area. Each night, big lake monsters and other legendary creatures like the famous Kelpies come out of the foggy waters of the Loch and attack the local settlements. Your clan must defend itself and chase these monsters into the open highlands or rivaling clans. The goal of the game is to find where the monsters are hiding, chase them away, and make your clan the strongest one in the area.
