Valve appears to be investigating the possibility of allowing Steam users to share their digital purchases with friends.
The move comes just a matter of weeks after Microsoft announced plans to offer similar service with its Xbox One console.
Kotaku reported that Steam users had discovered the code in the latest client beta. They revealed a "shared game library" that would enable users to let other accounts "borrow" a game.
The code in question is:
"SteamUI_JoinDialog_SharedLicense_Title" "Shared game library"
"SteamUI_JoinDialog_SharedLicenseLocked_OwnerText" "Just so you know, your games are currently in use by %borrower%. Playing now will send %borrower% a notice that it's time to quit."
"SteamUI_JoinDialog_SharedLicenseLocked_BorrowerText" "This shared game is currently unavailable. Please try again later or buy this game for your own library."
It is unclear if or when Valve will implement the feature.
Though it is possible move will be timed with the launch of the Xbox One.
