4 new dedicated multiplayer maps and 9 new weapons (including the AN-94 and the Bizon SMG). How to Install & Play (Official Method)

: Install the Steam or Ubisoft Connect launcher if you haven't already.

Searching for "free download" links often leads to "abandonware" sites or cracked versions. Be cautious:

: Search for "Ghost Recon" in your library and select "Install." Expansion packs like Desert Siege are often automatically included in the "Ultimate" or "Gold" editions.

: Visit a reputable store like Steam or GOG . Note that Desert Siege usually requires the original Tom Clancy's Ghost Recon to run.
