Zenless Zone Zero (ZZZ) Primer guide: All missions and rewards explained

The Primer in Zenless Zone Zero helps players progress by nudging them in the right direction and awarding incredibly useful currency along the way. This guide covers every Trial, mission, and reward, ensuring you don’t miss anything ZZZ has to offer.

All Primer missions and rewards in Zenless Zone Zero

In Zenless Zone Zero, the Primer is accessed through the Compendium via the main menu or at the top of the screen outside of commissions. Every Primer task rewards you with some currency, and completing every task in a Trial earns you a big reward and allows you to move on to the next.

While Primer tasks can technically be completed at any point, you can only claim rewards for your current Trial. Here’s every Primer Trial, task, and reward.

All Primer Trial No.01 missions and rewards

Primer Trial No.01 introduces you to Zenless Zone Zero’s core concepts and throws in a little currency to get you started. You’ll more than likely complete this entirely naturally within the game’s first hour or two.

Trial No.01 Completion Rewards: 50x Polychrome, 1x Master Tape, 2x Senior Investigator Log, 1000x Denny

How to upgrade an Agent’s Level

Levelling Agents is done manually through the Agents Menu with Investigator Logs. Select the Agent you want to level, select Basic Stats, and then the arrow next to their Level.

How to upgrade a W-Engine

For Genshin and Honkai Star Rail players, W-Engines are Zenless Zone Zero’s version of Weapons and Light Cones, respectively. Leveling W-Engines works similarly to leveling Agents, albeit with the W-Engine Energy Module resource.

You can level W-Engines in the Equipment section of any Agent by selecting a W-Engine, then Enhance. Alternatively, you can level W-Engines straight from Storage in the main menu.

Where to find Waterfall Soup in Zenless Zone Zero

Waterfall Soup is a delicious noodle shop on Sixth Street — directly next to Random Play — that opens after completing the Logistics Disaster Combat Mission. Since General Chop was the one to commission you, he’ll offer you a free meal on your first visit

All Primer Trial No.02 missions and rewards

Primer Trial No.02 introduces you to more Zenless Zone Zero gameplay elements, such as gaining materials and improving Agents and W-Engines. Like the first Trial, every Primer task in Trial No.02 is completed naturally through the main story.

Trial No.02 Completion Rewards: 50x Polychrome, 1x Master Tape, 2x W-Engine Energy Module, 15000x Denny

How to promote an Agent in Zenless Zone Zero

Once an Agent has reached their maximum level, you can promote them to raise their level cap. Select the Lv. Agent you want to promote, select Basic Stats, then select the arrow next to their level to promote them.

Promoting costs Certification Seals for your Agent’s role (e.g., Stun Certification Seal), which are obtained through Agent Promotion in Combat Simulation.

How to Modify a W-Engine

Modifying a W-Engine raises its level cap by 10. To modify a W-Engine, select it from a character’s Equipment tab or Storage, select Enhance, click the arrows next to its level, and then Modify.

You’ll need Components that match the role of the W-Engine effect to modify it, which are obtained through Combat Simulation. To grab some Components, select the Compendium, then Training, and W-Engine Modification.

All Primer Trial No.03 missions and rewards

Primer Trial No.03 is super easy to complete and awards the A-Tier Starlight Engine, which is a fantastic W-Engine for Attack characters at this point in the game.

Trial No.03 Completion Rewards: 100x Polychrome, 1x Master Tape, 1x Starlight Engine, 20000x Denny

How to get Engagement in ZZZ

Errands are simple daily tasks accessed through the Compendium. Completing an Errand typically earns you 100 Engagement, and you’ll receive a reward once you reach the maximum of 400 Engagement.

To equip Drive Discs, select an Agent, then Equipment. Characters have six slots, meaning one two-set and one four-set bonus can be active simultaneously.

How to upgrade Drive Discs

Drive Discs can be upgraded in the Equipment section of an Agent or through Storage. Select a Drive Disc, then Enhance, and click the arrow next to its level. Upgrading (leveling) Drive Discs costs Plating Agents, obtained through Routine Cleanup and Combat Simulation.
