This is the most technologically advanced place on Felicity Island -- featuring electricity, running water, and a sense of foreboding. Although it’s not clear exactly what happened here, the fact that this place was abandoned so quickly is still unsettling.
The Abandoned Research Base is a community lot located on the northwestern coast of Felicity Island. In this abandoned base there's an airplane (in which Sims can play in) and what seems to be a runway. There's also a lot of boxes and parts to gather. The story reward object in this lot is a grand piano.
