Arklay Laboratory

The Arklay Research Facility is where the original Resident Evil took place. (Also known as The Spencer Mansion.) It is disguised as a mansion in the middle of Raccoon Forest and owned by the Spencer Family, however, deep underneath the mansion is a research lab where deadly T-Virus and G-Virus experiments took place.

When Jill Valentine, Chris Redfield, and their team get to the mansion in the safety of Cerberuses, it is infested with demonic T-Virus creatures and zombies.
