CO-OP, challenges

[mahoganyman]

hey guys,  I had a quick question about the co-op mode.  I already cleared Steelport of all gang activity, but I still need to complete the challenge/trophy to taunt 50 gang members.  Is this able to be completed in co-op?   and secondly,  there's a challenge where you have to pay 50 compliments to people.  Is that to gang members/ enemies or just people in general? and (last question I promise)  do using cheats disable the ability to complete challenges and get the trophy?  I'm already max rank but there's still a few cheats that would help me out.  thanks for reading this somewhat long post

You have to taunt gang members, has nothing to do with co-op. Same with complimenting them. I think you can use both taunt and compliment on your own gang members in your headquarters.

 

I'm not sure about the cheats, they will likely disable trophies. Which cheats would you even want? You pretty much become invincible by the end of the game anyway...
