The latest Delta Force 2 patch is available through the auto-update feature in the game, or via direct downloads here and here (4.4 MB). This brings the version number to 1.04.14 (thanks DF2-Base.de for this bit), and the changes include additional Voice-Over-Net features and "some animatics for the fixed gun emplacements, however you still cannot use the emplacements" (thanks Maagic for that one). This accounts for the patch being about 1 MB larger than the previous version.
