Mastiff is a video game publisher responsible for bringing unique titles to North American audiences, including the rhythm games Technic Beat and Pump It Up: Exceed. They published retro-revival titles like Space Raiders and Space Invaders Revolution, as well as the children's game Easter Bunny's Big Day. The publisher is also known for its involvement with the Heavy Fire military shooter franchise.
Founded by industry veterans, the company established its early portfolio by licensing and localizing niche Japanese arcade and console properties. For the PlayStation, the publisher released
Easter Bunny's Big Day in 2003, targeting younger audiences with simple platforming mechanics. Collaborations with Japanese developer Taito led to the localization of
Space Raiders for the GameCube and PlayStation 2, which reinterpreted classic arcade shooting as a gritty, third-person sci-fi action game, followed by the dual-screen portable title
Space Invaders Revolution on the Nintendo DS.
In the music game genre, the company partnered with Arika to bring the rhythm-action title
Technic Beat to the PlayStation 2, featuring a distinct circle-based marker system and classic Namco soundtracks. This paved the way for the home console adaptation of Andamiro's arcade hit
Pump It Up: Exceed on the Xbox and PlayStation 2, which was distributed both as a standalone software release and as a specialized hardware bundle packaged with a proprietary five-button dance mat. Beyond these standalone releases, the company expanded into military-themed action, managing the development and distribution of the
Heavy Fire rail-shooter series across multiple console generations, alongside flight simulation entries within the licensed
Top Gun franchise.
