Hollow Zero has its own terminology that defines its unique mechanics and items. Before diving into this game mode, it’s essential to familiarize yourself with Resonia, Bounty Missions, Combat Configuration, Hollow Shop, and Corruption.

Hollow Resonium

While exploring Hollow Zero’s HDD system, you will encounter monitors with question marks. Moving to these tiles allows your Agent to choose among three power cards known as Hollow Resonia. Hollow Resonia come in different categories, butall of them are stat or skill buffs.

If you manage to collect four or eight of the same Hollow Resonium, you will get an additionalAdvanced Hollow Resonium cardin return. This process is called Catalyzation, though the catalyzed cards won’t be removed from the deck.

Bounty Missions

Each week at a specific time, Hollow Zero adds new Bounty Missions. These missions are divided into two categories based on their difficulty:Special and Common.

Common Bounty Missions are ranked S, A, and B, with S being the most challenging. You can complete up to three Common missions per week and have two chances per week to refresh these tasks. Special Missions, however, are not refreshable, but you can complete four of them weekly.

Shop

The Hollow Shop appears as an HDD tile in some regions of Hollow Zero. Here, you can purchase Resonia, buff, and healing items, or catalyze your Resonia to obtain better power cards.

Corruption

Corruption is a team-wide debuff that you are inflicted with simply because of exploring Hollow Zero. Once your squad has 100 Pressure points, they get a random effect that will negatively affect one aspect of their stats or abilities.

How to Unlock Hollow Zero

Hollow Zero unlocks once youcomplete Chapter One – Intermission quest. It will become accessible via the Compendium under the Challenges tab. However, you can also start investigations in the Scott Outpost, where you meet Ray for the first time.

Hollow Zero Rewards (License Level)

Exploring Hollow Zero’s infected zones rewards you with Investigation Points. These points contribute to increasing your Investigation License, which functions similarly to a battle pass reward system, granting you access to rare resources.

For successful Hollow Zero investigations, keep these notes in mind:

Exploit Hollow Resonia Synergies

Prioritize getting duplicates of the power cards you already have. This allows for unlocking more Advanced Hollow Resonia and gaining better abilities.

Choose a Striker as Your Leader

Given that Hollow Zero is a time-oriented game mode, it’s best to go in with a Striker.Agents with Striker Specialtyare hasty assassins, helping you clear each floor as quickly as possible.

Strategize Your HDD Movement

Try to minimize your movement, as stepping onto each HDD tile gives you ten Corruption points. If you want fewer debuffs in Hollow Zero, explore only the tiles that yield rewards or are crucial for your progress.
