No, I have no mods installed - though there are some available for graphics and textures.
It's surprisingly playable despite that - the only big let down is the enemies, who look like they are made of balled-up newspaper.
Someone was saying that they found it difficult to deal with that though, as they were expecting more 'body horror' - I'm playing along while keeping an eye on The Vintage Game Club
who are doing a playthrough. It has been useful to follow that and see that I'm not going to find out on Level 4 or whatever that I have completely fucked up my character build. However, it does feel a bit odd to be playing through with people who are applying a critical approach to the game while playing.
All that said, I am enjoying it (and I bailed on Deus Ex, to my shame) and it is a decent game.
Btw did you get to choose custom tattoos etc for your character in UFC? Pics?
