A 300-Swarmer Horde at Iron Butte Ranch that you clear in Keep Them Safe, part of the push toward Wizard Island. It is the only Horde you ever fight in Iron Butte, and it shows up just for this mission.
Horde KillerHorde Killer is the storyline for wiping out every Freaker Horde in Oregon. It mixes a few story missions with the open-world Hordes you find yourself, from small cave groups in the north to the huge swarms in the south.
Race Against TimeRace Against Time is a short late-game storyline that sets up the final push against the Deschutes County Militia. It picks up after Deacon rides north to Lost Lake and covers the plan to strike back at Wizard Island.Stock fire bombs, explosives, attractors and stamina cocktails before you ride out. Use choke points and explosive barrels, and never stop moving. A high-capacity LMG cleans up the stragglers once the fire has done its work.
You can ride off, restock and come back. The kill count holds for a while, but stray Swarmers top the Horde back up if you wait too long. Keep your bike fuelled and parked on your exit route, not in the Horde's path.
The fertilizer is for the giant bomb Rikki and Boozer are building to get onto Wizard Island. Deacon also notices many of these corpses carry Ripper cuts on their faces.

Wizard Island
Wizard Island sits in the middle of Crater Lake and is the Deschutes County Militia's main base. You work for Colonel Garret here, with Dee's gun shop and Caleb Tomlinson's garage as the draw.
Black Mountain Ridge
