I just started the UT2004 single player a couple days ago and I would like to change the difficulty level. I can't find any place to do that though. Is it possible? Let's say I was to get all the way through single player on the setting I'm at now...I think it's just like 4th from the easiest difficulty or something. Would I fail to unlock any models because the setting is too easy? Do you unlock more models if the difficulty is higher? Thanks for any help.
