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!

Best A-Rank W-Engine from the Bundle

The Vault is the Best Choice

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.

The Other W-Engines are Less Recommended

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.

List of All W-Engines

Starlight Engine Replica is a Good Alternative

Agent Specialties
Attack						Stun						Support						Anomaly						Defense

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.

Best Characters for Each Bundle W-Engine

All Bundle W-Engine Best Agents

W-Engine	Agent	Specialty
The Vault	Nicole	Support
Demara Battery Mark II	Anby	Stun
Housekeeper	Corin	Attack
Starlight Engine Replica	Billy	Attack

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!
