Use the sniper rifle to clean up the last of the invaders dwelling inside or outside the fort until the Minutemen give you the all-clear, then speak with Ronnie and Preston to complete this quest Fallout 4: How to get "The Last Minute" Gauss Rifle!Today I show you guys how to get the last minute gauss rifle. You need to complete old guns to get ronnie The Last Minute is a modification of the Gauss Rifle. The weapon looks slightly similar to its predecessor. You can initiate the Crippling effect on it to get 50 percent additional limb damage. Last Minute also features a shielded barrel, capacitor boosting coil, compensator mods and night vision scope.

Talking to Preston Garvey after having defended the Castle from the Institute's retaliatory attack will initiate this quest, provided the Sole Survivor has a total of at least eight settlements under their control. Otherwise, the quest Form Ranks will be given instead and must be finished Apart from the gang related perk and legendary weapon that you get at the end of the dlc's main story (2 out of 3), you also get grenade recipes from them. The Pack one, the predator grenade causes wild animals to run to the location and attack anything nearby. The Disciples one, the fury grenade acts the same way as the hallucigen grenade. Finishing Fallout 4's Nuclear Option quest this way gives you the Minutemen Ending, but you are now free to go piss off factions or supermax your character without worrying about the main quest. Get the Minutemen Ending. Just one loose end to tie up. Before teleporting, you're faced with a choice. The Last Minute is a bit heavier than a typical gauss rifle, but it's twice as accurate and has a slightly longer range to boot.
