forgot Monsters. Coop is really fun in that IMHO. I play it alot with my son and we have a blast frantically yelling where to build stuff and what in time for each wave of bad guys.
Coop in Pixel Junk Eden is sweet too - I just wish the levels didn't have the timer effect as I really like enforced time limits on my fun.
Try to be reasonable... its easier than you think...
