Players begin a new game by controlling the lead character Heimdall through a series of arcade-style trials. This includes axe-tossing (cutting a maid's braids), boar hunting, and fighting on a ship which influences the character's stats and the crew members they can choose during a playthrough. After completing the trials, the player then picks five characters to form a crew alongside the main character. While Heimdall falls under the class of "Chieftain", the others fall under typical classes. This includes the Warrior, Wizard, Shipwright, Navigator, Druid, Blacksmith, and
Berserker. These classes all differ in stats and skills and they each have their own strengths. While warriors make good melee fighters, wizards can cast spells more efficiently and identify scrolls and items more proficiently, while navigators can alert the player if travelling to another island might damage the party. The most critical stat of characters is energy and even though this can be replenished by eating food, any character who loses all of their energy dies and must be revived by magic. The game features three modes: Navigation Map, Island Exploration, and Combat. Island Exploration is conducted via an
isometric perspective, in which the player explores an island through different rooms. Players can take only Heimdall and two crew members with them onto the island, and can only leave through the entry point that they used. Most islands have a range of traps, including pits, spikes and arrows that can damage the player, along with monsters based on Norse mythology. In addition, players can acquire weapons, scrolls, gold, food, and various other items from either combat, treasure chests or just lying around. Some islands feature NPCs that can be interacted with, some of whom act as shops where players can buy or sell items. Combat begins when the player interacts with monsters at their current location, though some are triggered by moving past a certain point. In combat, the player must reduce the enemy's energy to zero while avoiding the same fate. Only one character may fight and they can use various weapons such as bare knuckles, swords, axes, and throwing daggers to do damage. They can also use spells, defend against attacks, or flee from combat. Attacks are done in real-time, and what weapons and spells can be used depends on what each character possesses in their inventory. If the player wins a battle, they may find loot from their opponent. The Navigation Map focuses on moving around the current game world the player is in, based on the main quest they are conducting. In this mode, players can rearrange their crew to denote who explores the island with Heimdall, as well as rearrange a party's inventory. Travelling between islands requires the player to choose a location they can reach from their current position. To reach a distant shore, players must move to an island that connects to it, but can decide whether to explore an island or continue travelling. The game features three major world maps to explore, each connected to a main quest to complete. ==Plot==
