I have a code for Xenonauts, which you can use to activate it on GOG.com (not Steam!) Again, the game does not activate on Steam, instead you need a GOG.com account. Price: 7 TF2 keys.
Would you be interested in a tradable gift that includes Half-Life 2: Deathmatch, Half-Life 2: Lost Coast, Half-Life Deathmatch: Source, and Half-Life 2: Episode One?
