Space Harrier 3D

Space Harrier 3D (スペースハリアー３Ｄ) is a rail shooter developed and published by Sega for the Sega Master System. It is a sequel to the Master System version of Space Harrier, making use of the 3-D Glasses to create the illusion of depth as the player flies into the screen. The 3D effect may be turned off with a code if the player doesn't have the required Glasses by getting a high score, then entering "THREE" as a name with the second Control Pad to enable the option.

Space Harrier 3D was included on Sega Ages 2500 Series Vol. 20: Space Harrier Complete Collection for the PlayStation 2 in 2005. As the original 3-D Glasses aren't compatible with the PS2, other 3D modes are available such as red/green anaglyph. It was later available on Sega 3D Fukkoku Archives for the Nintendo 3DS in 2014 and Like A Dragon: Pirate Yakuza in Hawaii in 2025 for multi-platforms.
