Valve has made its team-based online FPS Team Fortress 2 free-to-play on both Mac and PC.
Anyone who has paid for the game previously will be automatically upgraded to the Premium Account, which will grant you rare cosmetic items and the ability to store more items in your backpack.
According to Gamesindustry.biz, who reported the move, the game will now be funding entirely by in-game purchases such as clothing and weapon upgrades. However, a FAQ on the game's website stressed that all these items would be available as random in-game drops.
