WTT: Gift Codes- Garry's Mod, NS2, Serious Sam 3, humble bundle games.

[atom]

Here is a list of what I have:

Sanctum Collection
Sanctum 2
Orcs Must Die! GOTY
Orcs Must Die! 2
Garry's Mod
Serious Sam 3 BFE
Magicka + 2 DLC
Natural Selection 2

I have no interest in these. They are available in Humble Bundle gift links. I want to trade for games I might have more interest in. Also will take cheap GeForce that can do hybrid PhysX. I want Starcraft 2, I realize I probably will not get that lol. Send me your offers!
