Fair, I tried it back when it first hit steam and was using a friend's PC to game. She had a monster gaming unit while I was working with a cheap laptop for college.It's better with ads ons. One I have adds extra bosses. One is a giant skeleton dragon I will have to screenshot next time I play.
May show my age (mental and physical) but I highly recommend Castle Crashers and Battle Block Theater. BBT Co-Op no mic on PC was the true friendship test. (College lappy barely ran them, but it managed.)
