tl;dr - Helldivers 2 was removed for purchase on Steam for countries unable to create PSN accounts. This was not reverted.

tl;dr Steam Console command - Replicable results by performing: Run > steam://open/console > Execute command: package_info_print 137730

As many are aware, on May 6th Sony has rescinded their mandatory PSN account linking that was scheduled for May 30th. Although this is a big win, many are not aware that the same countries that were going to be restricted due PSN limitations have already been restricted on Steam as of May 4th (SteamDB - Change 23416542 - https://steamdb.info/changelist/23416542/). This was not reverted.

You can find current information regarding this through Steam console:

• Open Steam console (Run > steam://open/console)
• Execute command package_info_print 137730 (This is the command to print current information for 137730, which is the sub/package for Helldivers 2)
• Here’s the current output for that as of this posting:

Hope this helps put things into perspective. Come to your own conclusions regarding this.
