A slick-eyed forum goer on the Steam Gifts forums spotted a new entry on Steam Database for SEGA Halloween Bundle, but according to him, it was quickly renamed to the more generic Steam Sub 33119.
In either case, the bundle includes:
- Condemned: Criminal Origins
- Hell Yeah!: Wrath of the Dead Rabbit + DLCs
- Total War: SHOGUN 2 + Blood Pack DLC
- SEGA Genesis & Mega Drive Classics, including:
- Alien Storm
- Altered Beast
- Decap Attack
- Golden Axe
- Wonder Boy in Monster World
He surmises that it might actually be an Amazon bundle rather than something actually sold through Steam because it has a proof of prepurchase key attached to the entry.
