The A-Rank W-Engine Bundle in Zenless Zone Zero (ZZZ) provides Proxies with four A-Rank W-Engines to choose from. Check out which A-Rank W-Engine is the best one to get from the Bundle, which characters go best with it, and how to use the Bundle here!
| The Vault W-Engine Details | |
|---|---|
The Vault
|
Money-Lover • Dealing Ether DMG using an EX Special Attack, Chain Attack, or Ultimate increases all squad members' DMG against the target by 15% and increases the equipper's Energy Regen by 0.5/s for 2s. Passive effects of the same name do not stack. |
Of all four options, The Vault is the most recommended W-Engine to select. It's Nicole's signature weapon and synergizes well with her skills, which you will be using for a huge chuck of the game's early stages.
| W-Engine | Explanation |
|---|---|
Demara Battery Mark II
|
• Can be acquired for free at the early stages of the game. |
Housekeeper
|
• Recommended only upon unlocking Corin's Mindscape Cinema. |
Starlight Engine Replica
|
• Only viable for Billy. |
While the other options in the Bundle are also good picks, they are less recommended for the reasons above. Housekeeper is a great W-Engine for Corin, but works better if you have at least one of her Mindscape Cinema unlocked.
Starlight Engine Replica is only suitable for Billy, being the only Attack agent that can hit enemies from afar. Demara Battery Mark II, however, is second to the Vault due to Anby's Stun abilities which are useful in the early stages of the game.
| Agent Specialties | |||||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Just like the Agents who wield them, W-Engines also have corresponding Specialties. However, they can only be activated if they are equipped by Agents of the same Specialty.
You will only have three characters to begin with—Anby, Nicole, and Billy. If you already have a decent Support W-Engine for Nicole, selecting Starlight Engine Replica for Billy can be a decent alternative.
| W-Engine | Agent | Specialty |
|---|---|---|
The Vault
|
Nicole
|
|
Demara Battery Mark II
|
Anby
|
|
Housekeeper
|
Corin
|
|
Starlight Engine Replica
|
Billy
|
Each W-Engine in the Bundle are the signature weapons of the characters above. Taking a look at their passive effects, it will be clear that each W-Engine synergizes well with their wielders' abilities.
Once you opt to choose one, keep in mind the Agent you're going to equip it on for maximum performance!

To use the W-Engine Bundle, access your Storage and find it under the Key Items category. Once opened, you will be able to select which W-Engine you desire.
