Team Fortress 2 had Steam trading card support added in the initial test batch of trading cards on May 15, 2013. There are 9 cards in the series.
If you purchased the Orange Box or TF2 before it went free-to-play, you'll receive 5 cards at random for purchasing and playing the game. When playing as a Free-to-Play game, cards are earned by purchasing in-game content (approximately $9 USD per card drop).
