Z-Noid patch

After 28 January 2016, there are several update:

  • The addition of 12 difficulties: Easy 1 & 2, Normal, Hard 1-9.
  • Different difficulties give out different Daily ZS Clear Rewards.
    • This reward can only be obtained twice per day; once every 12-hours interval.
    • The player can choose what prize to be claimed. It ranges from common to rare items such as rare zombie tattoos and costumes.
    • The Reward Box can be upgraded. If the player obtains a box at low difficulty level, and does not use it yet, then he/she plays another game (in the same day) and obtains higher-leveled box, the higher-leveled box will replace the lower one.
  • The players can now earn dollars and level up by just shooting at the zombies.
  • If the player uses Round Retry item, all players will respawn immediately, instead of running the round all over again.
    • However, all players just have 1 chance to retry, no matter who use the item. If the players still loose the second chance, the game will end.
  • The respawn time has been set to a limit of 120 seconds, increasing as players level up.
  • Zombies are now labeled with a new set of colors to identify their behaviour, they will be common in the hardest difficulties.
  • Removed items: Dr. A's Trunk, Secret Map, Research Tools, Zombie Sample and Confidential Documents.

As previously stated, players are able to obtain a Reward Box twice per day upon successfully finishing a Zombie Scenario map. The amount of items, duration, quality, quantity and rarity is based on the box level.
