The Santiam Tunnel NERO Checkpoint is a Lost Lake checkpoint at the choked Santiam Tunnel, south of the Berley Lake Infestation. It pays Iron Mike's Camp and holds an injector.
Cut or shoot the loudspeakers before you turn the power on, or they blare and draw Freakers. Then get the generator running with fuel, a new fuse or a reconnected cable, depending on the site.
With the power on, the NERO trailer opens. Inside are the NERO Injector, which raises Health, Stamina or Focus, and the Intel Recorder. A powered checkpoint becomes a fast travel point.
Berley Lake Ambush Camp and the Berley Lake Infestation are both close and pay Iron Mike's Camp.
