You should collect resources to upgrade your shelter and survive the zombies attack in this mode. Make a radio call within the time limit and request for rescue. Destroy the enemy’s shelter to prevent upgrading of the shelter and request for rescue.


The objective of the mode is to win by calling backup from a radio. This can be done by collecting resources after fully upgrading your shelter. The game will be divided into two parts during a round, Day and Night.

During the day, the players will have to collect resources (wood and metal) scattered around the map. These resources will be the most essential object in the game as you will need them to upgrade your shelter. Beware of the time limit and other players as they will try to steal your resources and/or attack you.

During the night, the zombies will start attacking each player's shelter. You will need to defend yourself for this.

As time passes, your hunger meter will decrease. If it reaches zero, your health eventually decrease as well until your death. It is advisable to keep your hunger meter full.

Also, zombies move slower during the day but run faster during the night. Money can be obtained by killing zombies and other humans.

  • When the game has started, there are wood (3 quantities) and steel (3 quantities) near your shelter. Try to harvest 2 of 3 each of them everyday as they will regenerate back to 3 in the next day. If player depletes both of them, they will never appear again in next day and so on.
  • You can find an M3 & TMP near the police car near your shelter or Scout at bottom places. Pick those weapons to protect yourself from zombies or other players.
  • Collect resources as many as you can, don't forget to return to your shelter when the clock is ticking.
  • Be sure to buy ammo for your Browning M2HB heavy machine gun as it helps a lot when fighting against zombies.
  • Always repair your shelter to avoid getting it destroyed by a horde of zombies or players.
  • Be careful when you reach the final upgrade and activate the radio, your rivals will come to destroy your shelter. Always protect your shelter until the radio reaches 100%. If your rivals have successfully destroyed your shelter, your radio call process will stop and you will have to call it again from scratch and start from 0%.
  • There is a Hunger bar under the wood and metal icon. You must keep an eye on it because when the meter is empty, your player will starve slowly until you die. There are 2 ways to refill your hunger bar:
    • By collecting red cans (meat can) until the meter is full.
    • If you died, you will respawn 7 seconds later with the hunger bar fully refilled.
  • You can't respawn if you're dead at night, also you can die if someone or zombies destroyed your shelter.
  • When you're dead at day, you can respawn after 7 seconds but you will lose a few of your resources.
  • When you kill someones, they will leave a bag. Loot that bag to get the resources from your rivals.
  • Build Sentry gun to make sure your shelter is safe in the morning.
  • Be careful when collecting resources because zombies and other players can attack you easily from behind.
  • This game can be played alone.
  • When using the Browning M2HB heavy machine gun, try to fire in 5-round burst to control the recoil easily as it runs out very easily.
  • When the night starts, be sure to have the Shelter Repair in progress, this will restore your shelter health points which can be helpful.
  • There is a buy zone at the middle of the map, where players can buy weapons and equipment.
    • Machine guns with very high clip size are recommended in this map, since all guns will have 1/3 of their reserved ammunition in this mode.
  • A bag with some of your resources and money will be dropped if you are killed by a zombie or an opposite player, be careful as possible when attempting to loot it.
  • During the night the skin of the zombies will turn into green. Moreover, they run faster and deal higher damage. It's recommended to stay home than look for resources.
  • As more days passed, the stronger zombies will appear.
