Team Fortress Portal, a German Team Fortress 2 fan site, has claimed to have found all 36 achievements for the medic, not yet revealed by Steam. The image outlines all of the different achievements medics will soon be able to earn, and as shown, many require the effective use of team play and game experience. You can check out the full list of achievements below, along with an image that shows each achievement's individual badge. If this turns out to be correct, we can hopefully see a statement release from Valve soon.
