It was, I saw it too when I ran it an hour or so ago. I think they swapped it with Zombie Night Terror since I don't recall seeing that one at that time.
It appears there was some house cleaning done on Steam today. I had no cards in my inventory this morning and came home to see almost 8 pages worth of them, none of which can be sold. All of them were garbage games that were given away (I think it's Zonitron games). Thanks Gaben for the +20...
I've requested a refund for a game almost a month later and they still gave it to me, so it's possible. I was surprised it went through, but it was just sitting in my inventory at the time.
Did steam change something with how it counts games? I was around 6040 and today I'm at 5993.
On the plus side I get to have another forgettable bundle trash game be #6000 again.
