Collections are a record of the weapons and armor obtained throughout your account's progression in SAS: Zombie Assault 4. They were added to Flash on February 3, 2015 and to mobile in version 1.4.

Rewards[]

The rewards of the collections are obtained by collecting all weapons and armour of a specific category from strongboxes (Championship reward weapons are an exception) or by simply crafting them. Each category of weapons' rewards (obviously) only apply to weapons in that category. The same applies to armour.

Other Facts[]

  • The rewards from collections are account-wide, and the progress is also account-wide.
  • Items obtained and sold before the collections update do NOT count towards collections progress.
  • Very low level characters seem to not receive the collection rewards that yield Strongboxes other than the full weapon and armor collections.
  • You do not need to keep the weapons in your inventory to get the rewards. You just need to have encounter them from the strongboxes.
  • In the mobile edition, you have to get one of each type to unlock their respective bonus. This makes collections more difficult.
    • This encourages players to create additional characters to finish all their collections of the guns they haven’t unlocked.
  • Z-Arm weapons are not included in the Collections. Their names wouldn't be mentioned in Top Records even if you used them to maul down most zombies.

Achievements[]
