This level consists of Tentacles, organic creatures with arms that rapid fire at the Vic Viper. The arms can be destroyed by shooting the discolored segment on their arms, to which the Tentacle will simply float away. The core itself can be destroyed, but it takes many hits before they explode, so it's often best to just destroy the arms, and let the Tentacles float away. At the end, the player must face a rush of many armed Tentacles, followed by the Big Core for the final time.
- The music track of this level was later remixed for the Big Core MK I in Otomedius Gorgeous.
- This is the only level in the game which does not feature landscape and obstacles, but just one type of enemy in outer space.
