Noooooo, Deathsmiles 2X has been refused for the October reward offer. I guess it is expected since it has more of a Christmas theme than horror theme. I had really hoped I could just knock out the October reward offer with just that one purchase, and now I will continue to wait for a better opportunity to get any sort of discount on it. I will try to edit the OP to reflect the revealed information that both games in the series do not qualify by the forums (by XBLRewards5).

Now I hope the Plants Vs. Zombies table for Pinball FX2, the DLC characters and music packs for Castlevania: Harmony of Despair, and the F.E.A.R. 2 DLC to even consider a combination of potential purchases which could actually take advantage of the reward offer. I really do hope for some confirmations soon, I do want to make some purchases.

EDIT: Despite the OP listing The Dishwasher: Dead Samurai as a non-qualifier, I thought I saw on the forums that it did apply to the reward offer. Just saying the OP may have this title listed incorrectly.

EDIT 2: I changed the OP to show The Dishwasher: Dead Samurai as eligible based on this link
