Saints Row studio Volition is to reveal a new game later this week.

The upcoming project will be shown for the first time during a PAX Prime panel in Seattle on Friday August 29.

"The developers behind the Saints Row franchise invite you to participate in a quiz show hour with Natalie Lander, the voice of Kinzie," reads a description of the event, which will take place from 10am-11am PDT (1pm-2pm EDT / 6pm-7pm UK).

"At the end of the panel, we'll show you exclusive gameplay, art, and details for an upcoming project from Volition."

Panelists will include Volition creative director Steve Jaros, Volition producer Jim Boone, voice actress Natalie Lander, and Aubrey Norris, brand director at Deep Silver, the games publishing label of Volition parent company Koch Media.

It was revealed in July that Volition intends to grow its headcount to around 300 staff by hiring 100 new employees.

Details of the Champaign, Illinois-based studio's expansion plans were released as a result of an application to the city for financial assistance in remodelling Volition's office.

Volition was acquired by Koch Media as part of the THQ IP auction in January 2013. Koch Media paid $22.3 million for the studio, reportedly beating off competition from Ubisoft.

Volition's most recent game was Saints Row IV. The open-world title was released in August 2013 on PC, PS3 and Xbox 360.

The studio was also previously responsible for THQ's Red Faction games, although that franchise was acquired by Nordic Games
