Attention Helldivers, Due to technical issues at the launch of HELLDIVERS™ 2, we allowed the linking requirements for Steam accounts to a PlayStation Network account to be temporarily optional. That grace period will now expire. See details below in this post. Account linking plays a critical role in protecting our players and upholding the values of safety and security provided on PlayStation and PlayStation Studios games.
Yeah, allowing the game to be sold in regions where PSN isn’t available was a huge fuck-up. Sony and Valve really dropped the ball here.
