Back in the camp, talk to Kieran who’s been tied to a tree. After the cutscene, Kieran will lead you back to Six-point cabin where some of the O’Driscolls are holed up. Throwing Knives will be added to your inventory as well. Bill and John will be joining you in this mission as well.
Keep riding until you reach the cabin Kieran is talking about. Make sure to equip your preferred weapons before dismounting your horse, including the throwing knives. Follow Kieran to the outskirts of the cabin. Crouch to trigger a short cutscene. After that, you’ll have the option to send Bill or take the lead to take out the pisser. If you decide to deal with the first target, make sure to use your throwing knife for a silent kill.
Next, approach the two other O’Driscolls and stealth kill them with Bill’s help. Keep an eye out on your radar to know the enemies’ line of sight. Continue and take out one more enemy by the log. After that, your party will be in position so it’s up to you if you’ll take out the outer guards stealthily or get into position to surround the enemies before engaging them. In any case, you won’t be able to take them all out silently so make sure you’re in a good position before opening fire.
After clearing all enemies around the cabin, take your time in looting their bodies and use your Eagle Eye ability to spot some items you can pick up. To continue with the story, head to the cabin to trigger a cutscene. After the scene, the others will head back to camp while you check the cabin for some loot.
Use your Eagle Eye to spot the items and containers you can loot. Don’t forget to pick up the Double-Barreled Shotgun over the hearth. If you have a Gun Oil in your inventory, you can clean this weapon up to improve its stats. Finally, search the chimney to get the hidden $600. Half of it will go to the gang and you’ll get to keep the remaining amount. Mission complete.
