GameStop's listing for Spore Creepy & Cute Parts Pack is back, and this time it's official. Along with officially announcing today the first add-on pack for Will Wright and Maxis' evolution simulator Spore--10 days after it was spotted in the specialty retailer's online database--EA also revealed the game's first expansion, which will focus on the Space Age.

As previously reported, the Creepy & Cute Parts Pack will be available for PCs and Macs beginning November 18. The add-on will include in excess of 100 new creature-building parts that will fall in line with the titular theme. The parts, available in the game's Creature Creator, include components for the body, as well as paint options, animations, and backgrounds.

EA has told GameSpot that pricing has not yet been confirmed for the add-on pack, but the aforementioned retail space has the game listed for $19.99. Further, the pack can be used with both Spore proper and the retail version of the Spore Creature Creator, released in June.

Spore's first full expansion, which EA is currently referring to as the Space stage pack, will arrive in spring 2009. The expansion will give space-borne civilizations Star Trek-esque teleportation technology, letting players beam down to distant planets and undertake new missions. The expansion will also add in the Adventure Creator, which will let gamers build and share their own missions. EA did not reveal pricing information for the Space expansion.
