Soon you'll see Black Mesa available on Steam for a relatively low price. But we aren't dropping all support for the free version. In fact shortly after the Steam release there will be a completely new free version of the game. We also plan to open source our maps and some game assets to the modding community!

Purchasing the Steam version of Black Mesa is more about supporting the team and our efforts than anything else. However, the Steam version will include features that the free version simply can not have. We will be paying careful attention to feedback, and you'll have a very real say in how the final game turns out.
