The Searchlight east church is a location within Camp Searchlight in the Mojave Wasteland.
The church is in east Searchlight near the school and the Searchlight fire station. It consists of a single empty room that has lost most of its roof. In the back of the room, there is a cellar door to the Searchlight church basement. It's on the other side of town from the other church where Logan and his crew are taking refuge.
The Searchlight church appears only in Fallout: New Vegas.
