To close out a week of update announcements (and updates!), Valve had one final surprise in store for Team Fortress 2 players tonight, offering the first 11,111 players to reach this hidden site a shiny new medal.
Being limited, the offer is of course already done for, all 11,111 medals claimed within a matter of minutes. Were you one of the lucky ones? As you can probably tell from that screengrab there, I certainly was. Even though I don't really know what it is/does.
Shame I can't poach it on eBay!
