From Australium to Zepheniah Mann
"TF2 didn't start with a lot of story. There wasn't room for one. But as the updates got more ambitious, we found the perfect way to explore the mercs' world: comics. Over the years, the comics have spawned ancillary characters, then assistants to the ancillary characters. Companies mentioned in passing became global empires three generations old. The game that started as a handful of guys in a desert shooting at each other slowly blossomed into the most labyrinthine story in Valve history."
The Team Fortress 2 Comics are promotional comics used in large updates for the PC, but do contain information regarding the Classes and history of the World known as Team Fortress 2.
