[H] Half-Life 2, HL2: EP1, bundle keys [W] CoD: Modern Warfare 2 (MW2), Alpha Protocol, keys/offers

EDIT: Proteus is gone.

HAVE:

Steam Wallet funds (somewhat flexible on this one)

-Half-Life 2 (gift)

-Half-Life 2: Episode 1 (gift, plus some steam wallet to make up the difference)

-Titan Quest (key)

-Warhammer 40,000: Dawn of War (key)

-Awesomenauts (key)

-Capsized (key)

-Dear Esther (key)

-English Country Tune (key)

-Intrusion 2 (key)

-Oil Rush (key)

-Tiny and Big in Grandpa's Leftovers (key)

WANT:

-Call of Duty: Modern Warfare 2

-Antichamber

-Alpha Protocol

I'm willing to trade Half-Life 2, Half-Life 2 Episode 1, or up to $7.50 worth of Steam goodies for either MW2 or Antichamber on a 1:1 basis. I'm also looking for Alpha Protocol on the off-chance that anyone here has it. The steam keys are negotiable and I'm generally willing to trade those on a 3:1 or 4:1 basis, plus sweeteners from Steam Wallet.

Also accepting TF2 keys - 3 for HL2, 2 for EP1, 1 for Warhammer, Dear Esther, or Awesomenauts, and 0.5 for the other steam keys.

(Episode 1 is probably worth less than the other two 1:1 options, so I'll pitch in something extra from my Steam Wallet to make up the difference)

Thanks!
