The fairly open sightlines will give the survivors an advantage in the beginning, but there are few weapons for ranged encounters. Save ammo as if they were Bells. Tom Nook's famous starting store, Nook's Cranny, functions as the featured holdout, but you can go as far as the cliffs or tracks too. Play it with normal infection modes, or tweak traits to your favorite setting.
