Some weather events offers additional features that players can take advantage into. Specifically during winter season and rainy seasons.

Snow Cloud.png Winter Weather

  • During winter season, all bodies of water such as Coast, Swamp, Radioactive Swamp and Crater (filled with water) will turn into Ice. Players will be able to travel in ice-covered bodies of water as they would normally do inland.
  • Players will not be able to use Handmade Raft,Motor Boat and Motorized Raft for the duration of the weather event. However, walking and travelling using vehicles on Ice increases the movement speed of the player.
  • Players will not be able to gather Dirty Water from all bodies of water however, they can extract Ice from it and turn them to clean drinking water. Players can use tools when extracting Ice, similar to cutting down Firewood from the forest.
