1 will often have 2 forges, 2 dew collectors, and 1 of each of the rest when playing solo. When playing in a group we tend to have multiple workbenches so we can crank out ammo much faster.
I NEVER have screamers, but I am NEVER using any torches/candles/generators so my heat rarely gets high enough to trigger them.
Does heat generation increase as gamestage increases? I keep reading about people struggling with screamers and I never encounter them
