Monday Night Combat Screenshots (PC)

I really like the sense of humor in this game, and the different classes are a bunch of fun too.  Now there's even a free to play sequel in the works.  Huzzah!

A.R.E.S. Screenshots (PC)

A.R.E.S. is a very short Mega Man clone.  Not a bad game if you can get it on the cheap.  Wait for a Steam sale! =D
