Grand Ages: Medieval

Bandit camps are the small wooden structures you will find randomly throughout the game and are protected by bandits, to destroy them might take quite some force. To find them you need the naked eye as they don't pop-up on the map. You'll know one is close when your carts start to be attacked by bandits, look around there. Some people state that bandit camps are hard to find and suggest to use a sandbox game with the full world to be sure you'll find 5. I used the "middle" map which is small and found 5 without much issues. Also I've got a feeling there are more bandit camps in multiplayer but I can't confirm this. Simply find and destroy 5 bandit camps randomly in the world and the trophy will pop.
