Zombie night: once a day the zombie night starts with an in-game night (usually 20 min). There is an announcement 2 min before, and a countdown runs at the top centre. Zombies spawn in small groups near you – but only while you are outside. Inside your base (in range of your tool cupboard) and in safe zones you are safe.
Every zombie you kill drops some scrap and sometimes supplies. Your kills and your rank are shown in the countdown. At the end the three best hunters get scrap and season pass XP, and everyone sees the ranking of the night.
Treasure race: all online players get the same treasure map (a note in the inventory) with the grid square at the same time; a golden circle on the map shows the target area and shrinks at half time. Whoever types /dig close enough to the treasure first wins the main loot (elite crate and scrap), places 2 and 3 get smaller prizes. If you are still too far away, /dig tells you how close you are. The race lasts 20 min at most.
While they are running, both events are listed under "Active events" and in the event schedule.
