Stranded on a desert island, Spy vs Spy the Island Caper sees the spies attempting to escape in a waiting submarine. Their goal is to collect three pieces of a missile before the volcano erupts, avoiding obstacles such as quicksand and sharks along the way.
The game features new traps, including hidden pits, napalm, snares, and a pistol, which can be used against each other. Hand-to-hand combat has also been replaced with sword fights, adding a new layer of strategy to the gameplay. With seven difficulty levels, players will need to adapt their tactics to overcome the challenges.
