格罗斯洞窟基地

The 格罗斯洞窟基地 is an Unexplored Territory in 异度神剑X. It is a Ganglion base located in caverns directly beneath 黑钢大陆's 戛纳宫殿, and can only be accessed by crossing the lava field northeast of 第505区FN点. It must be entered on foot, as the entrance is too small for Dolls. As with all Unexplored Territories, its discovery yields an achievement (Invading the 格罗斯洞窟基地).

The entrance to the Antropolis is blocked by a transparent 伤害护甲 which cannot be removed until a key is obtained during 歼灭蒂法尼亚, and similar 伤害护甲 block access to parts of the Antropolis until three more keys are obtained during the mission.
