We finally get a look at Shovel Knight's face and, surprise, he's an amphibian of some sort.
While some files within the game hinted at this, developer Yacht Club games' tweet today showing off the First4Figure of helmetless Shovel Knight has confirmed that the shovel-wielding hero is a strange frog person. Considering the world has goat people, magicians, and flying rats, a frog knight is not hard to imagine.
Shovel Knight originally released on PC, 3DS, and Wii U, then expanded to pretty much every other system under the sun. The upcoming and final DLC, King of Cards, is scheduled for 2018.
