In the woods there are anomalies. They are dangerous, zeds and players like to come there too. They look like black monoliths with a weird glow and make a huming sound. If you walk into the monolith you get teleported to a forest on a different location on the map, the downside is you random lose some health and sometimes an item when teleported. When you come out of the teleport you spawn random 100-150 meters from an other monolith in a different forest. This will give you a chance against survivor/bandits that loot other survivors. Or zeds that immediatly jump you. I would definitely use them...
