How to Play Hollow Zero: Lost Void

Step-By-Step Guide

1. Select Investigation Strategy
2. Gain Buffs From Collecting Resonium
3. Use Gear Suited for Your Team
4. Get Mottled Ether Particle for Gears
5. Check the Map and Plan Your Routes
6. Unlock and Increase Your Combat Potential

Select Investigation Strategy

Before you head into the Hollow Zero, players can select an Investigation Strategy in the Battlefront Purge menu. You can select from various strategies, each having its unique effects.

Choose one that benefits your team the most. You can unlock an Explorer's Badge for your collection by clearing Battlefront Purge: Difficulty V with a Tier 3 General Gear.

Gain Buffs From Collecting Resonium

Similar to previous renditions of Hollow Zero game modes, Hollow Zero: Lost Void also offers players Resonium that gives different effects to your team.

Collecting Resonium will give you a ton of advantage over your enemies, especially in high difficulties.

Use Gears Suited for Your Team

Talk to Ray at the entrance to the Hollow Zero: Lost Void to select your gear. These gears grant different effects such as reducing Decibel requirements and provide you with a Bangboo that can assist your team in battle.

Each gear has its different effects, so make sure to choose one that is best suited for your team. You can also increase your gear level by completing a Combat - Gear node.

Get Mottled Ether Particle for Gears

When you're starting in the Hollow Zero: Lost Void, there will be gears in the selection that are locked. You will need to get a Mottled Ether Particle to access these gears.

Mottled Ether Particle can be obtained by completing a run of Battlefront Purge.

Check the Map and Plan Your Routes

Make sure to constantly check the map to plan which node you want to go to. Each node will also have different symbols that let you know

Red nodes typically mean that you'll be fighting against enemies, a Light Bulb symbol means you can usually get Resonium for free, green nodes as a place to heal your characters, and yellow nodes are where you can buy Resonium.

Unlock and Increase Your Combat Potential

You can unlock Combat Potential to give your team some buffs or effects that will be useful in your Hollow Zero: Lost Void run.

You can also use a maximum of 5 Expertise Points on Combat Potential you've fully unlocked to increase their buffs even more.
