Gunbare! Game Tengoku: The Game Paradise 2

Summary

PlayStation-only sequel to Jaleco's crossover cute-'em-up. The system uses a gun controller connected to the 2P controller socket to provide cover fire for the shooter. The title of the game is therefore a combination of Gun and the Japanese word Ganbare (Don't give up!). Even if you don't have a gun controller, you can use a DualShock controller to shoot for cover.
