Viking raids are a type of expedition accessed using maps purchased at an explorers' hall. The map leads to a tiny island denoted with a Viking helmet icon in the ocean view. Firstly, pirates man the guns at the shore fortifications (gunnery puzzle), regardless of performance on the gunnery phase the vikings will descend upon the island, then either a swordfight or rumble takes place on the island. If the pirates win the brawl, PoE are placed in the ship's booty and hold. This type of expedition was released to production oceans during release 2011-01-19.
