THANATOS-5 Confirmed Set[]

THANATOS-5 Confirmed Set

With this set, the player can get the THANATOS-5 for sure from Craft using the Perfect Pick Recipe item, but the durability will determine the period of the weapon.


  • It takes 4 seconds to change the mode from normal to Thanatos form while 2 seconds in contrast.
  • The grenade's quantity is unlimited. However, the player can launch only one at a time.
  • When exploding, the grenade will separate into 4 smaller ones, each of them keeps splitting into 4. In total, there are 3 times of splitting and 16 grenades after the last time. Each splitting time takes 2 seconds. There are a total of 21 explosions.
  • Each grenade explodes instantly if it comes in contact with a body.
    • Each grenade also deals a small amount of damage if it explodes on the user, but the damage is negligible enough to be avoided as long as the user is still wearing a kevlar.
Zombie Modes

In A mode, it can deal 29 ~ 180 damage per shot to zombie, while in B mode it can deal 300 ~ 4,000 damage per grenade. Using this weapon in confined spaces such as Assault's ducts as a supporting weapon is highly recommended.

Zombie Scenario

In Zombie Scenario, the T-5 is a perfect crowd control weapon if the player are facing a cluster of zombies. In terms of damage, T-5's primary fire can deal 30 ~ 150 damage per shot to bosses, while its alt-fire it can deal up to 2,000 ~ 10,000 damage per grenade. Having all grenades hit the bosses' body continuously, will deal a generous total damage of 200,000+. Despite that, it's not a great weapon for destroying barriers.

The Thanatos-5 is most recommended weapon to use should the players are looking for an easy HARD-9 clear daily. A full team wielding this weapon with Secret Research Funds can tackle Double Gate at the highest difficulty.
