I got a key for Hitman: Sniper Challenge from someone, it didn't activate properly on Steam, contacted support. This was their response: 'This subscription is no longer avialable for registration.'
So I kindly advice you to not trade it anymore.
Its traded, but it was gift. Its strange because in my inv had discription that includes Hitman Abs, Hitman Sniper Challenge, but when i traded it, in someone other inv it looked just like normal hitman abs. (it hadn't description includes Sniper Challenge:/) I think its because of other region of the world.
BTW. I also have hitman abs standard edition
Yeah, someone else also commented that iot might be a region thing. Well, I asked support, but no reply so far.
Just spammed that message to all trade topics about Hitman: Sniper Challenge, to avoid awkward trade moments. :)
I have copy of Hitman Absolution which includes Sniper Challenge
I'm interested in TF2 Keys (12 keys)
