A Time-Limited Event in Scenarios

Starfall Inversion - Limited Time Event
The Starfall Inversion is a limited-time event that begins between 9:00 AM and 9:00 PM in-game time, which translates to approximately 30 minutes in real-world time.

Zero-Gravity Tide Effects

Starfall Inversion - Mechanics
In Starfall Inversion, there is a set time period during which the world enters a Zero-Gravity Tide State. During this state, the world experiences low gravity mechanic, resulting in significantly reduced gravity and slower fall speed. This effect applies to all Metas and vehicles. Additionally, it increases your inventory's maximum load.

Zero-Gravity Tide starts at 9:00 AM until 9:00 PM in-game time, giving players a total of 30 minutes (real world time) to play through it!

Collect Gravity Crystals

Gravity Crystal in Inventory

You can collect Gravity Crystals to get rewards from the Starfall Collection event. You can get Gravity Crystals by defeating enemies, opening Unstable Aggregates in the air, and opening Star Advent Loot Crates.

Note that you can only collect them once the Zero Gravity Tide is in effect.

You can use some of them outside of the event, but you will have fewer chances to do so, as you won't be able to stay in the air for long.

How to Survive the Starfall Inversion

Starfall Inversion Tips


Grab the Gravity Tide Set

Starfall Inversion - Gravity Tide Set
You can spend Starchrom at the Wish Machine or open Star Advent Loot Crates to obtain the new Gravity Tide Set. Simply having one piece of the set increases your jump height, which you can take advantage of during the Zero-Gravity Tide.

Additionally, the 4-piece bonus effect of this set provides a massive damage increase while you are floating mid-air. This will occur frequently during combat due to the effects of the Zero-Gravity Tide.

Always Carry Event Items

Starfall Inversion - Gravity Tuner
To fully take advantage of the Zero-Gravity Tide, it is highly recommended that you carry gravity and event related items such as Gravity Tuner, Gravity Neutralizer, and Floating Aerogel. These items can drastically alter how you move during the event.

Equip Mods with Downstar Suffix

Starfall Inversion - Mods
Mods with the Downstar suffix generally increase your damage against enemies below you. Since you will often be in a higher elevation compared to the enemies due to the nature of the event, you can consistently take advantage of this effect.
