TF2 Gets Unlockables

Yep, that's what's happening. Comrade Francis from PC Gamer UK is over at Valve playing the new map stuff for TF2, and he's posted some details over on C&VG.

Starting with just two new items for the Medic, Valve are going to be gradually rolling out new, unlockable weapons for every class. These will be alternative versions of their current loadouts that, once unlocked by earning a certain number of achievements, you can pick and choose from on a new 'Loadout' menu.

It sounds like Valve are just experimenting at the moment, so there aren't many concrete details. It will expand the options available to the various classes however, which will inevitably please some players while infuriating those who thought they have the game nailed down.
