Blue Stinger is an action survival horror game released in 1999 for the Dreamcast game console, developed by Climax Graphics and originally published by Sega, with publishing rights outside of Japan obtained by Activision.

The environments in Blue Stinger are entirely 3D. Players heal themselves in real-time using food and drinks bought from vending machines, forcing players to heal only when it was safe. Combat consists of purchasing weapons and ammunition in the same manner, including swords, rocket launchers, napalm launchers and triple-barreled shotguns. Eliot starts out with a pistol while Dogs starts with a crossbow. Besides shooter game elements, the game also uses beat 'em up elements when weapons are not equipped.
