Yes, it’s that time again. The Heavy update will be dropping a bunch of maps, unlockable weapons, and achievements, just like the Pyro and Medic updates before it. So! You can check out the mystery achievements here, but as I found out, the achievement image files are named according to the achievement’s requirements — “tf_heavy_kill_scouts.png” and so on. Click below for a screenshot of all of them and make with the names what you will!

Clicky for the big version. Sorry, it shortened some of the file names and I’m in a hurry to post so I can’t fix it.
