Valve promised us more information on the Heavy update
each weekday, and they did not disappoint. Today we have some juicy bits of information for you concerning the new achievements and the new melee weapon for the Heavy. First, the weapon. Dubbed the K.G.B. (or Killing Gloves of Boxing), they give the Heavy guaranteed criticals for 5 seconds if he kills an opponent with them. It appears, though, that it has a slower attack speed, and it take a full second and a half to switch to the minigun and wind-up to fire, reducing the impact of the critical bonus.
Second are the achievements. Notably, a lot of them deal with the interaction between the Heavy and the Medic. There are some interesting ones that appear to reveal more about the upcoming weapons. For example, Marxman and Five Second Plan both appear to show a weapon that has not been revealed yet. A mine? Return of the infamous MIRV from Team Fortress Classic? We'll find out soon enough! You can check out the full list of achievements and Valve's comments on the K.G.B.
