to pick the charcter go to multiplayer oiptions and pick it from their
some of the characters are allies other axis so check both lists!
to use the maps extract them using example A
then pick them from the place in the start a new game
some are objective, roundbased team match, free fr all etc so check all of them
you have to put them in the map rotation since they are not in the standard map rotation

final comments
try the skins they sometimes dont work, i think that the person who is hosting has to have the skins on his comp.
so if u peeps get them on ure comp we could use them
