Ironman, honestly Captain America? Pssh what has he got? Honestly, he has a shield... and some 6 year old's dress up costume. But Ironman on the other hand.. Genius, hilarious, billionaire, chick magnet and his costume is just badass!
Checkout the adventure map: Flint & Steel Adventures. I personally loved playing that map! Had awesome different challenge rooms, scared me, annoyed me, made me laugh. All that good shit, so check it out and maybe base it on something like that, good luck.
