Not a commemorative foam beard and bow-and-arrow set or anything, but nearly as good: a free dynamic theme to spruce up your PS4, and an avatar set to make your PlayStation Network presence all the more fearsome.
The developers at Santa Monica Studio have seen the passion of God of War fans - all the cosplay, videos, fanart, music, fun in-game selfies, and even a recreated scene by completely with Lego blocks - and in return gave them a warm tribute to their dedication and creativity.
"I'm very happy to indulge you with a small token of our appreciation".
Both will be free in the PSN Store, and you don't need to own the game to access them.
"Yet, change is hard". "Change to a longstanding franchise comes with immeasurable doubt, a studio defining risk and a huge leap of faith".
"Thank you from the bottom of our hearts for embracing the new God of War and for helping Santa Monica Studio rise up to a new beginning as well. We made this journey together".
The theme itself is available to download, for free, right now from the PlayStation store, and depicts everyone's favourite God slayer Kratos and his precocious young son Atreus rowing across the wonderfully serene Lake of Nine - the imposing mountains and Jörmungandr, the colossal World Serpent, easily visible in the background.
Speaking of anniversaries, this year also marks the 20th year since Sony Santa Monica was formed. This recent news from Barlog has just unfortunately hammered the nail down into the possibility coffin of God of War having a DLC.
In addition to creating and developing the God of War series, the Sony studio has collaborated with other developers to deliver various PS2, PS3, PS4 and Vita games.
