Top bit of info to know before your bonce explodes in rage, however - I bounced a quick mail to Valve’s very own Saxton Hale, TF2 lead-guy Robin Walker, who reckons there’s some sort of bug in the system that’s meaning people aren’t getting unlocks even after hours of play. “Not at all how it’s tuned,” apparently. Which is, I think, the first time I’ve been relieved to hear a game has a bug - it means the problem will get fixed. Read on for my thoughts on the change and word on how it’s supposed to work from the goodly Mister Walker.
