Patapon 2 Remastered is a port of the PSP Patapon 2 game for the PS4.
However with no updates on the release date of Patapon 2 Remastered since the 2017 announcement, and the rumored departure of Hiroyuki Kotani from Sony, fans have speculated that the game was silently cancelled.
In the God of War: Full Length Feature, it is possible to see a Patapon 2 icon right next to the Patapon 1 Remastered, but as noted by Krvavi Abadas in the Resetera forums, the video was recorded about 3 months after the Patapon 2 remaster was announced.
Around December 24th 2019, PSN tracker "Gamstat" listed Patapon 2 Remastered for America, Asia and Europe regions and a "Don Chaka" version for Japan region. Games listed on Gamstat's tracker usually means that the game will be announced within a couple of weeks.
On January 30th, at about 01:30 AM in Europe, Patapon 2 remastered was released. It was found to have several differences from the original, chief of which was the removal of the multiplayer feature of the Patagate. To make up for this, when you first unlock the Patagate, the game gives you every piece of friendship equipment, and the lordly hairpiece.
