They got Avatar Awards in my Left 4 Dead 2

Speaking crap you can get for your Xbox Live avatar...

Apparently way back as early as October, some hacker got into the unpublished achievement list for the game, and came across some extra text at the end of the file that made reference to "Avatar Awards". Subsequently, Valve has confirmed their existence, and what is required to unlock them:

Med Kit

Unlock the Med Kit by beating all five campaigns on any skill level.

Frying Pan

Unlock the Frying Pan by killing 10,000 Infected.

Garden Gnome

Unlock the Garden Gnome by rescuing Gnome Chompski.

Bull Shifters Shirt

Unlock the Bull Shifters shirt by winning 10 games of Versus.

Left 4 Dead 2 Shirt

Unlock the Left 4 Dead 2 shirt by winning 10 games of Scavenge.

Zombie Hand Shirt

Unlock the Zombie Hand shirt by killing 10,000 Infected.

Depeche Mode Shirt

Unlock the Depeche Mode shirt by rescuing Gnome Chompski.

Which reminds me, I have yet to see the legendary Frying Pan in-game, so maybe we should call a L4D2 for HoC Nite this week. Fair warning.

Via lots of sites, but GamertagPics had the best picture.
