If you have a huge nuke on you and you wish to use it, do one of these things before activating the nuke.



If using the nuke to clear out any zombies in an area, place a bedroll far enough away from the nuke.

Store anything in your inventory that you wish to keep inside a locker or a metal wardrobe thats away from the explosion or at your base (hopfully your base is far away from the nuke too).

Once you have nothing except the nuke in your inventroy, you're good to go with starting World War Th-, almost made an obvious joke right there.

Have fun :)
