From the website:
The unlockable for the Heaviest pugilists out there is the K.G.B. Any time a Heavy kills an enemy with the K.G.B he receives five seconds of guaranteed critical hits. This crit-boost can be used to punch and kill further enemies, extending the boost time. Alternatively, the Heavy can switch to another weapon and use the boost to take out an enemy at range. The Heavy’s slow movement speed, and the K.G.B’s slower swing speed, make it a risky prospect.
This is almost completely identical to a rumor floating around lately about leaked details of the new Heavy achievement weapons, citing a “slower crit based fist weapon, a Minigun that slows down enemies, and a sandwich that recovers health”.
Those who have downloaded the Icon pack for the new achievements will find that most of the names already give away what they are, and how you get them. One, namely Konspicuous Konsumption, even helps support the unlockable sandwich theory, with the name “tf_heavy_eat_sandwiches.png“.
What’s truly surprising is the Spyalectical Materialism icon, which seems to have a Spy holding a pistol with a Silencer.
Could it be that Valve has already given away what may be a new weapon capable of making the Spy not useless after the new Pyro updates? We can only hope.
EDIT: Achievement definitions

Pyros got something that helps them against spies in the update?
I don’t think so.

It looks like the spies wearing a gas mask too. Love this info, very cool. I play on the XBox though, so no update for me =( Tempted to buy it for PC though. It’s only ten bucks right? Sounds insanely worth it.
