Gray Zone Exploration
"We're not at an optimal state yet, commander."
This article is a stub. You can help us by expanding it (check our quick editing guide and how to guides).
Gray Zone Exploration (灰域探查) is a game mode added with client 3.0200. The 6th Detachment of the Border Surveillance Corps has returned from a previously unexplored area with great loot, so the Commander has decided to deploy more exploration parties.
Players deploy echelons on a map of hexagonal tiles and capture them to earn points and unlock prizes from the ladder. Tiles contain a small battle map which is entered by expending Exploration Permits (or resources of the player has no permits remaining). Harder fights grant more points, and bonus points are granted for occupying every tile on a map. Time will pass with each battle, switching between day and night battles every three turns. In this mode, damaged T-Dolls will automatically be healed to full health after being withdrawn, unless they are in the Critically Damaged state. Battles can be automated with the AI Proxy Battle function.
Past exclusive equipments can be earned from the rewards ladder, while past exclusive T-Dolls can be dropped from battles. Each season of Gray Zone Exploration rewards different exclusives.
Nodes
- Battle Node: play a standard battle map.
- Boss Node: play a boss battle map and earn bonus points.
- Fairy Node: assign a Tactical Fairy to a premade echelon that will fight a normal battle.
- HOC Node: assign a HOC to an echelon.
- Incident Node: adds a battlefield effect.
- Land of Encounters: a mysterious area that is only revealed when on an adjacent tile, leading to Collapse Rift special puzzle maps.

Rewards
The rewards ladder progresses as the player collects points. During the start of a new season, the rewards listing will have 2 layers, the upper layers will contain 
Basic Equipment Indicators at 2000, 4000 and 6000 points respectively while the lower layers will contain extra rewards.
The Basic Equipment Indicator at 2000 points will let the player select a normal 5-star piece of equipment. At 4000 and 6000 points, the reward is a Basic Equipment Indicator which lets the player select a past exclusive piece of 5-star pieces of equipment including some new exclusives restricted to Grey Zone Exploration.
After the ladder is completed, it will reset the reward bracket to 0 and remove the 2nd layer of rewards for the rest of this season. The rewards from the upper layers will remain unchanged.
