If playing in Steam, tap ALT+F12 (to remove the HUD), and then F12. Make sure to change the original F12 keybinding (which is like, Modify UI, or something). It'll save the image on both your harddrive and can also be uploaded to the Steam servers.
Alas, my dear friends. It is with some sorrow that I now tell you of the passing of our friend Bruiser. He had some trouble with the New Purple Gang. He retreated into the icy realm of Canada to lick his wounds and never returned. We can only assume that he has been killed in action.
*sad moment over*
It is now with great joy that I would like to introduce you to a new Behemoth, a holy fighter. I give you... El Santo de Lucha Libre!!!!!!!1one
