Together with Maxis, several students of the University of Southern California have developed a mini-expansion pack for the Sims 2. This is reported by SimsOvernight. Carrying the title "Sims 2 Spooked" the pack contains 20 objects, designed and developed by students, from a Possessed Coffee Pot to a "Frank – the Do It Yourself Monster Kit". The students were given Edith, the tool Maxis uses to create objects and more for the Sims 2, as well as some other tools, to create the expansion pack. The group of 22 was also advised by several Maxoids during the development. It seems that the pack was already finished early last year, but it's only been discovered by Sims fans recently. SnootySims also reports that, coincidentally or not, the idea of the expansion pack was mentioned in an early survey that showed up on the official site last year.

For more information about this mini expansion, see the news page, and their project page where you can find movies, a guide to Edith (with complete wiki about the tool), and a original gameplay concepts and ideas, as well as a full handbook explaining the different items in the game. Whether the expansion pack is available to the public is not clear at this moment.
