Valve releasing updates and content for free is no surprise. It's a practice that's today most readily apparent in the developer's fantastic support of Team Fortress 2. With dozens of new weapons and unlocks added since the game was released as part of The Orange Box back in 2007, it's a much different and in many ways better game today. Unfortunately, that applies mostly to the PC version. Xbox 360 gamers haven't enjoyed the same kind of constant support.
