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.
It’s exactly a money thing.
Publishers are usually responsible for all the shit people get angry about, but they’re also footing the bill to build the thing years ahead of time.
