If you're in Japan right now, then fellow TMNT players, you're out of luck because the TMNT: Cowabunga Collection was delisted from Steam a week ago.
However, for the time being you can still buy and play the 13-game collection on other available platforms (Nintendo Switch, PS4, PS5, Xbox One, & Xbox Series X | S).
Any PlayStation players from the UK can get their hands on selected Konami titles at discounted prices for a limited time and add any one of these games down below to their current PS4/PS5 libraries, including:
Super Crazy Rhythm Castle (-30%)
Metal Gear Solid Master Collection - Vol. 1 (-20%)
Super Bomberman R 2 (-30%)
Teenage Mutant Ninja Turtles: The Cowabunga Collection (-50%)
Take your pick (or buy all of them) because these deals won't last. Sale ends after January 5, 2024 (06:59:59 EST).
Artwork for a video I’m working on. The good thing about the Cowabunga Collection is that you don’t have to resort to emulators to play the older TMNT games. It’s not that emulators are bad or anything but it’s nice to have official ways to play these games again for a new generation that most likely doesn’t have access to the original copies of the games or even the original hardware needed to play them. I hope we get another collection with the games from the 2003 series!
