Now that we've settled into regular releases of content, we've found ourselves wanting a better way to talk directly to the TF2 community about the state of the game and some of the reasoning behind the choices we're making. Our hope is that this blog will accomplish that, and give everyone some better insight into our development process as well.
Our hope is that we'll be providing you with a variety of interesting things to read, whether you're a hardcore TF2 player or you've just started. We'll be going into the details behind some of the gameplay, posting a bunch of the concept art we haven't released before, and showcasing the great content the community is creating.
In the meantime, if you haven't checked it out yet you can read up on the details of the Pyro pack.
