The Steam purchased version works perfect -- once one critical step is completed.
1)Install Steam using C4P/Crosstie
2)Install Hexen II
3)Download uHexen II
here. Make sure to get the 32Bit Windows version. This updated Q1 port supports the expansion too, so if you have that, you can install that alongside Hexen II.
4)Unzip the contents over the Steam installed files. The files will be located
~/.cxgames/Steam/drive_c/Program Files/Steam/steamapps/common/hexen 2
5)In GNOME 2 you will be asked to merge the files or not, please do the merge. And when prompted to overwrite, please do so.
6)Run Hexen II in Steam as you normally would.
7)You can now set your game settings ingame just fine, as we are now using the updated exe :
Happy gaming!
