Grab his uniform to get one of the best unique outfits in the game, which is the Minuteman generalвЂ™s outfit. Power armor will be a huge benefit here, and energy weapons in general will do a quicker job against sentry bots.ДЄfter defeating him, make sure to take note of the former generalвЂ™s body on the ground next to a terminal. ItвЂ™s a typical sentry bot, so the key here to avoid taking damage head on or allowing it to get close for melee attacks. The tunnels are guarded by Sarge, a former defense bot which is still active. Still, if youвЂ™re worried, having power armor on might be a good idea given the boss fight youвЂ™re about to enter as you walk further in. Some radiation will also be present, but it shouldnвЂ™t be too strong. ThereВ are also a bunch of mines around, so keep an eye out for them. Watch out for turrets as you walk inside, though they should be very straightforward to deal with. ItвЂ™s a short underground area with mostly trash and a bit of loot here and there. The tunnels arenвЂ™t a particularly difficult area to traverse. Now you should be able to freely enter the tunnels. TheyвЂ™ll come in handy later on when you need to build some objects for the Castle. Hover over the rubble in front of your and scrap the trash into materials. To clear the spot, just enter the workshop mode. SheвЂ™ll ask you to clear the area so you can access the tunnels underneath. Just walk around with Ronnie Shaw and eventually sheвЂ™ll point out an entryway thatвЂ™s completely overflowing with rubble and dirt. ThereвЂ™s only one way inside the underground tunnels of the Castle. However, since the doors wonвЂ™t budge the only way in is through the tunnels. Although a bit tough, she means well and needs your help rearming the Castle.ДЄccording to Ronnie, thereвЂ™s an armory filled with goodies and blueprints for artillery behind sealed doors. SheвЂ™s a Minuteman veteran, and although youвЂ™re the acting general of the faction, respect doesnвЂ™t come easyВ with her. Upon arriving to the Castle, youвЂ™ll be greeted by a brand-new Minuteman character known as Ronnie Shaw. Ronnie Shaw will request that the Sole SurvivorВ returns to the Castle to discuss something with her. This settlement is located in a massive, old-time fort that needs to be cleared of Mirelurks and their queen.ДЄfter the fight, wait for three days and the call to return to the Castle should pop up through the Minuteman radio.

This quest will inevitably pop up eventually if you interact enough with Preston GarveyВ since heвЂ™s infamous for giving out more and more settlement quests.

In order to even start this quest, you first need to take the Castle.
