>Also is there a name for the thundercrack events at night that spawn new enemies? Does it always occur?
Enemies spawn from those broken uh, rift thingys? If you hear a thunder and enemy appears, then you can also hear zapping noise when you're close to the source anomaly. Follow the bzzzzzzzzuuuuuuuuuu, then shoot whatever black threedimensional ink splatter you see

Loot goes even better than that sometimes.
