Shovel Knight was an amazing game, with a lot of positive reception upon its release. (You can see my personal video review here) Luckily, Playstation platforms will get the Shovel Knight treatment with an added bonus; fighting one of their most iconic characters.
Kratos, of all things, will be featured in-game as a boss. He is no pushover, and has been stated that it will take some effort to even start the encounter.The game does promise rewards for defeating him, perhaps an ability or two? 
Regardless, it is an awesome addition that is sure to attract more attention to the game, and hopefully they can find a way to incorporate this into existing editions? (Please copyright, be nice!)
