New to the site, so sorry if this is explained somewhere else! We like to play defend maps, but we would like to try some new maps. I have found the various sites (including this one) where we can download new maps, but they don't specify whether or not the option defend is available for co-op maps. Do all co-op maps have the option of playing in defend mode? We would like to try some maps with interesting starting positions and LOTS of baddies. Any suggestions?
