UDK Blank Install ::: May 2011 [PC] file - UDK Developer's Group

This is a stripped down version of the UDK. All UT3 assets and code have been
removed, only the absolute minimum required to run remains. The blank install,
as provided, will NOT function properly at first, you must enter your own
details in the config files before it can run. This is intended for people who
already know their way around the config files, but hopefully everyone will be
able to follow these instructions. I made this for myself, and I figured others
might have a use for it. Yes, I am well aware something like this was made long
ago, but it has been incompatible for awhile now.
