Well it looks like the shit has really hit the fan for Helldivers 2. Arrowhead Game Studios, or Sony, have made it compulsory to link your game account to the Playstation network which has caused plenty of anger in the HD2 community.
Creating a Playstation account is free and you do not need to have a physical Playstation console, and it only takes a minute or two to create an account. However, it would appear that some countries are blocked from creating a Playstation account which means HD2 will no longer work in those countries.
Refunds are apparently being granted by Steam even if you have gone over the 2 weeks and 2 hours of playtime.

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. This is our main way to protect players from griefing and abuse by enabling the banning of players that engage in that type of behaviour. It also allows those players that have been banned the right to appeal.
As such, as of May 6th, all new HELLDIVERS 2 players on Steam will be required to connect their Steam account to a PlayStation Network account. Current players on Steam will start to see the mandatory login from May 30th and will be required to have linked a Steam and PlayStation Network account by June 4th. PlayStation Network accounts are free and easy to set up using this link:

We understand that while this may be an inconvenience to some of you, this step will help us to continue to build a community that you are all proud to be a part of.
Many thanks for your continued support of HELLDIVERS 2!
