Sites like MyAbandonware host the original 2009 ISO of DFX2. This is not legal, but it is safer than Steamunlocked because the files are unmodified 2009 disks. You will still need the WineD3D fix above.

Delta Force: Xtreme 2 (DFX2) is a tactical first-person shooter developed by NovaLogic, released in 2009. As a sequel to Delta Force: Xtreme, it focuses on large-scale military combat featuring vast open environments, drivable vehicles (tanks, helicopters, boats), and both single-player campaigns and large multiplayer battles.

Key Features:

GOG.com sells a fully patched, DRM-free version of Delta Force: Black Hawk Down (the superior game from 2003). It works perfectly on Windows 11 out of the box for $9.99. Wait for a sale—it drops to $2.49.

The official NovaLogic servers for the Delta Force series were shut down years ago.
