Hello everybody.
The Grotto Caves Horde is part of the Horde Killer story line and it’s located in the Cascades A.K.A. Mark Copeland territory. This mission is unlocked after you complete the Shadow Of Death and Ascending From the Underworld missions.
Make your way back to the Grotto Caves area. There was an Infestation at the Pioneer Cemetery there earlier in the game and it’s where you spied on the Nero Helicopter for the first time. When you get close look at your map to see the three possible locations. I assumed they would be in the caves so that’s where I looked first, they weren’t there but they could’ve been. I ran across them at the second location I checked, it’s actually better, in this case, to take them on in the open. The horde was on the move so I took cover in some bushes that they would pass. I used an attractor bomb first to get them to move away from my position but no all of the horde was lured away. I should’ve used another attractor bomb but instead I threw a couple of Napalm Molotovs, the second one was too close and they sniffed me out . I ran back around to the lake shore where there happened to be marauders on the dock, at this point the horde separated into two groups. After the marauders were taken out I got closer and shot the Freakers as they came out of the water. I then ran back up the hill to see the last of the horde going back to the caves. I went further when I didn’t get the mission complete notice and found one Freaker that was at the head of the pack.
Compared to the hordes that are in the other areas this one is small and as long as they don’t overwhelm you they are easily taken care of. I don’t know how much XP you’ll earn but you will get 550 credits, 1600 camp trust points, and the Horde Killer story line will be updated.
Thanks for watching, God Bless and happy gaming.
