The Old Sawmill Horde in Lost Lake is the biggest Horde in Days Gone, at 500 Swarmers. You have to clear it in I'll Save Some For You so the creosote truck can be filled. Stock up on fire and explosives before you ride in.
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.Walk the mill before you start and plan a loop. The yard has explosive barrels, loose log and plank piles and shelving you can drop. Tight gaps between the buildings funnel the Horde into a line.
Carry as many Molotovs and napalm Molotovs as you can craft, plus frag grenades or pipe bombs. Keep health and stamina cocktails ready, since stamina is what keeps you ahead of the pack. Save the LMG for the last hundred or so.
You do not have to finish it in one go. Hit it, run until it loses interest, and it heads back to the mill. Most Swarmers will not turn on you while they walk away, so you can shoot them in the back.
Once the Horde is gone, Deacon fills Rikki's truck with creosote. That truck is the bomb meant for the Wizard Island assault.
