The company’s founder Andrew Eades confirmed the news via Gamesindustry.biz, saying that the Brighton-based developer was letting go of all it’s employees effective immediately.  

Buzz! launched in 2005 and became something of a sensation for the developer, with the series spawning 18 games in total across the PS2, PS3 and PSP systems. The series innovated with the inclusion of buzzers - specialized controllers featuring different colored buttons that corresponded to the on-screen answers.

Buzz!: The Big Quiz, the second entry in the series, netted the studio a BAFTA award for Best Social and Casual Game in 2006, and the series boasts lifetime sales in excess of 10 million copies. 

In 2009 Relentless released its first self-published title, the episodic murder mystery adventure Blue Toad Murder Files. 

The closure is something of a surprise given the recent announcement of the company’s plans to expand to Wales. The Pontypridd studio, funded in part by the Welsh government, was expected to create 70 new jobs.
