As some of you are aware, the team behind UQMHD disbanded before they could finish their project. There was one attempt to fix some of the major flaws called UQMHD Remix, but unfortunately there were still a few more issues. Now part of a larger project also incorporating cheats in both UQMHD and Classic plus other patches a man who goes by the moniker "Kohr-Ah Death" has just finnished adding that extra polish the UQMHD so desperately needed.

You can get it on his website here. Both MegaMod of UQMHD and Classic UQM are available there.

I highly recommend all the optional downloads, which include Remix's changes as well.
