I'm interested in the Thievery mod, but I noticed a line in the download links:
"it will install over UT"
I have never installed an Unreal mod before, so I have no idea if this means I won't be able to play UT again or what. Can anybody help me out?

I think they just mean it installs into the UT folder. I've played it, and it doesn't interfere with UT at all.

Ok, thanks!
