16 Raids: when?

Bases can be raided at any time

Raids possible at any time

24/7
raids possible, 7 days a week
x5
damage divided by up to 5 while the whole group is asleep
  • There are no raid hours: a base can be attacked by day or by night.
  • When the whole group is offline, the offline shield greatly reduces damage (see “The offline shield”).
  • After an attack, the base goes on alert, then under seals (see “Alert & seals”).
Why?No raid hours, but a base is never defenseless: while the whole group is asleep, the offline shield divides damage by up to 5.
TipThe Défense tab (defense) of your workbench shows your base's shield, alert and seals live.

The blast

Up to 6 neighboring pieces take damage, only if the explosion can see them: nothing goes through a wall, a floor or the ground.

Offline base

The shield divides damage by up to 5 (see “The offline shield”): a metal wall can take 25 plastic explosives.

Where to find them

Plastic explosives + detonators in military and industrial areas; claymores, grenades, 40 mm grenades and firefighter axes are more common.

Melee tools

× 1 firefighter axe, axe, sledgehammer, pickaxe
× 0.7 hatchet, crowbar
× 0.2 knives, bats, fists…

Every hit wears the tool down: 500 hits and it is ruined.

WarningThe inner side of a wooden wall is weaker than the outer side.

20 Alert & seals

A raid wakes the base up… and then protects it

RAID≥ 500 HP in 30 minALERT1 h after the last hit · 3 h maxSEALEDuntil 2 h after a member comes back · 24 h maxCOOLDOWN24 h without new seals

During the ALERT

  • No placing or building
  • No upgrading or repairing
  • No demolishing
  • Members near the base are notified (start / end)

While SEALED (for intruders)

  • All pieces invulnerable
  • Doors, shutters, codes: blocked
  • Storage, barrels, workbench, tents: closed
  • Members' vehicles: locked

Applied if a wooden or better piece (or a locked door) was destroyed.

Who counts as “present”?

  • The members
  • The occupants: those who have the code to one of the base's locks (7 days)

Damage done by members and occupants does not trigger anything.

Example

03:00An intruder blows your door with 3 plastic explosives
ALERTThe base is frozen, members on site are notified
04:10No hit for 1 h: the alert ends → SEALED
10:00You log back in: seals lifted at 12:00
