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.
Better than the last issue IMO. Still hilarious and surprisingly heartwarming at times (Heavy looking out for his family, Soldier falling in love, etc.)
