[H] Guns of Icarus Online or Paypal [W] Sword of the Stars: The Pit and Mind Games

I have SOTS: The Pit (steamgift) to offer you. I don't really want Paypal but I am interested in TF2 keys. How many TF2 keys would you offer for it? You can buy TF2 keys from the Steam Market here: http://steamcommunity.com/market/listings/440/Mann%20Co.%20Supply%20Crate%20Key
