In what is likely to be a controversial (but not unpredictable) move, Valve has added microtransactions to their hat-simulator Team Fortress 2. The new Mann Co. Store functions much like the PSN store, only for items: put cash into your wallet, buy some items, use them. No gameplay-altering item is store exclusive, and most of the cosmetic items aren't either. A few, however, can't be acquired through drops and are solely available through the store now, like the Gentlemanne's Medal. We're really skeptical about the addition of microtransactions, especially given that there's no way to use the store using earnable currency like scrap metal. It's solely for paying customers.

Besides the microtransactions, this newest update adds the long-awaited trading feature, the ability to gift items, the Polycount pack, minigames (although we don't know what kind), and in-game customizable items. The item system is currently down in-game, presumably because it is being hammered by players. There's also a humorous comic which offers an in-universe explanation for the system.

Update: In addition to the new in-game trading and buying system, Team Fortress 2 is currently on sale via Steam for just $9.99, a 50 percent price cut from its normal price

Full patch notes after the cut.
