The International Game Developers Association is investigating L.A. Noire developer Team Bondi following reports of brutal working conditions at the Australian studio.
IGDA chair Brian Robbins told Develop that it intends to look into claims made earlier this month and wants to hear from any affected Team Bondi employees.
"Certainly reports of 12-hour a day, lengthy crunch time, if true, are absolutely unacceptable and harmful to the individuals involved, the final product, and the industry as a whole.
"We encourage any Team Bondi employee and/or family member to email firstname.lastname@example.org with comments about the recent past and current situation - positive or negative."
Staff at the studio have reported being asked to work 110-hour weeks during crunch periods, often without overtime pay. Studio boss Brendan McNamara was accused of being abusive to staff, while 130 developers have complained of being left off the game's credits.
McNamara then offered little in the way of denial or apology when asked to answer the accusations earlier this week.
