Steam is the largest PC games platform, and its Free To Play section is a permanent category of games that carry no price tag at all.

The line-up covers big multiplayer shooters, MMOs, card games, racers and co-op titles, and each one can be added to your library and played indefinitely without ever paying.

All you need is a free Steam account and the free Steam client for Windows, macOS or Linux. In-game purchases are optional in many of these titles, but nothing is required to download and play.
