Okay, basically this is a news story about pre-ordering
Left 4 Dead 2 and by doing so, getting Bill's virtual hat from the first game for your guys to wear in
Team Fortress. Yup, a pre-order deal.
That said, it's quite nicely put over at the
L4D2 site.
"And lest you think this is just some marketing gimmick, here's the intricate back-story justifying it: while conducting a science experiment on parallel dimensions, Bill's hat fell off a table into the
Team Fortress universe."
Give them a point for humour we say.
