The Rogue Tunnel NERO Checkpoint is the only checkpoint in Iron Butte, northeast of the Redwood RV Park Ambush Camp. It pays Iron Mike's Camp, and its memo shows NERO was cleared to use extreme force on the Rippers.
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.
Redwood RV Park and Wagon Road ambush camps are nearby and also pay Iron Mike's Camp.
