Orc must die 2 complete pack

It activates with all but the soundtrack DLC (I got mine from that bundle as well)

I'm not sure but I bet those HB Jumbo keys don't grant a gift (a 2nd copy) in your inventory, that's probably why it was removed from the giveaway list. The subID you posted includes 3 DLCs: https://steamdb.info/sub/18202/apps/

AND:

OnPurchaseGrantGuestPassPackage1 Orcs Must Die 2 - Complete Pack 2 Gift (18203)

So 2 copies in total.

I guess the HB keys activate this: https://steamdb.info/sub/16923/apps/

With this other package you don't get the 2nd copy as an inventory gift. Also, it's not available on the Steam Store.

I asked for the pack to be added, here's what I got as an answer:

"It seems that there are two seperate Complete Packs, where the difference is a single dlc:

https://steamdb.info/sub/16923/apps/ base + 2 dlc
https://steamdb.info/sub/17881/apps/ base + 3 dlc
I can only add the one with three dlc, but there is a chance someone will incorrectly make a giveaway using a gift copy that only provides 2. Since I cannot add both to the list, I'll keep it off for now. Since you no longer have a gift copy of the game, I take it that you are no longer interested in giving it away on this site.

If you still wish to give away a copy of the complete pack, let me know and I will reconsider this issue. Otherwise, take care and have a great week!"

The one I traded for a week or so ago didn't include the soundtrack.

Just create a ticket asking to add the game to the giveaway list.

You can also go a GA for just the base game if you wanted. The winner would have no issue marking it as received since he did get what the GA is for (and more).

I won a GA recently for the base game that was actually the game +2 DLCs. A very nice win.
