This classic 1993 puzzle-platform strategy game strands you as three Vikings—Erik, Baleog, and Olaf—after being kidnapped by aliens. The core gameplay requires you to switch between the trio, utilizing Erik's speed, Baleog's combat/ranged attacks, and Olaf's shield for blocking or gliding to solve intricate environmental puzzles. Success depends on chaining their unique abilities, with infinite retries available if a Viking falls. It's a test of tactical coordination across bizarre, time-displaced locations.
The gameplay loop requires players to strategically switch control between the three Vikings: Erik, Baleog, and Olaf. Each character possesses a unique set of abilities essential for puzzle-solving and traversal. All three Vikings share three health points, which can be depleted by enemy attacks or falls, and they can utilize items such as food to restore health, as well as keys and bombs to interact with the environment.
The primary distinguishing feature of this title is its mandatory reliance on character synergy. Success hinges on understanding when and how to deploy the specific skills of Erik, Baleog, and Olaf in sequence to solve complex environmental puzzles. If a Viking is lost, the game allows for infinite retries, encouraging experimentation without severe penalty.
Players must guide the trio through distinct, often anachronistic, settings following their escape from the alien vessel. The structure demands careful planning, as players must often use one Viking's ability to set up the next Viking's action, creating intricate chains of events necessary to clear a path forward. The game blends elements from the Platform, Puzzle, and Strategy genres.
