Rum and Gun is an adventure game about the difficult life of pirates. They survive by robbing, killing and plundering settlements on new lands. But the local aborigines are unlikely to be happy if a bunch of armed men try to take away their resources. Therefore, each participant in the robbery always risks putting their own life on the line. The main character has been sailing the seas almost all his life and is used to this way of life. He just regularly drinks rum, plays cards with his sailors and organizes concerts on old musical instruments. He is always accompanied by a loyal team, ready to support in difficult times and allowing him to pull off any business.
