Valve's roll-out of new achievements and unlockable weapons for each of the Team Fortress 2 classes continues next week. A patch updating the minigun-toting Heavy will be released on Tuesday, August 19th. This week, Valve will slowly reveal the full details of the update on the TF2 blog.

The "Killing Gloves of Boxing" is the first new weapon the Heavy class will receive in the patch. They're boxing gloves that replace the Heavy's normal bare-fisted melee attack. While the Heavy can't swing as quickly with the gloves on, any killing blows dealt by the K.G.B. will give the Heavy five seconds of automatic critical hits. That's critical hits with any weapon, mind you, so you can punch out an enemy and then switch to a ranged weapon to mow down his friends. Should be fun in melee-only sudden death, too.

The KGB will be unlocked after you completely roughly a third of the thirty-five new achievements. The icons and names of the achievements were revealed along with KGB on Wednesday, but not the actual descriptions. Shacknews noticed that the filenames of each of the achievement icons give you a pretty good indication of what the achievement will generally involve. For example, the filename for the "Communist Mani-Fisto" achievement is "heavy_kill_crit_punch.png."

The patch will also include a new control point map (cp_steel) and a second Payload map (Badwater Basin). They're also promising "a new game mode with five new arenas", which seems like a pretty beefy update to the game in its own right. As I mentioned earlier, the TF2 blog will provide a little more information on the patch each day so go bookmark it.
