The third class to get class specific achievements and unlockable weapons in Team Fortress 2 will be the Heavy, director Robin Walker has revealed.
Writing on the official Team Fortress 2 blog, Walker said that the goal of the pack would be to "make the Heavy more viable when he has no Medic to pair with."
While he doesn't detail how the development team plans to do this, Walker does talk about the problems about creating the pack.
Chief among them appears to be not changing the Heavy's role of a tactical tank or encroach on other roles.
The updates to the Tank follows the Medic and Pyro class packs, the later of which was released two weeks ago.
