This is the closest to you will ever get. You can literally zip this folder, upload it to Google Drive, share it with a friend, and they will be playing in 5 minutes.

: Since the game is no longer for sale on Steam or the EA App , you must use your existing backup files or find community-hosted versions.

Obtain a copy of the game files (often available as a "portable" or pre-installed folder from community sites like the Battlefield Bad Company 2 Reddit ). Place the game folder on your drive (e.g., C:\Games\BFBC2 ). :

: If the game won't start, you may need the DirectX End-User Runtimes and Visual C++ Redistributables .
