Grounded 2 introduces several essential items necessary for players aiming to enhance their base-building capabilities and strengthen their defenses. Among these are the elusive disks, which are scattered across the game’s vast map.
While these disks are marked on your in-game map for easy location, they can be tricky to access as their positions might be elevated or buried underground. In this guide, I will offer insights into locating the first disk, known as Optical Disk A, and navigating obstacles to successfully retrieve it.
Finding Optical Disk A

Optical Disk A is conveniently located near the starting point of your adventure, making it one of the first collectibles you will encounter. However, approaching the indicated spot will initially reveal nothing visible, with no apparent way to descend to it.
To retrieve the disk, head north of your location to find the entrance of an anthill. This will lead you down into the depths, where the disk is waiting.
Exploring the Anthill

Upon entering the anthill, you’ll find yourself amidst various cans of bug spray. No immediate enemies will threaten you, transforming your exploration into a navigation puzzle. To expedite your journey, consider utilizing your Red Ant Buggie to zip through the confined spaces.
Be cautious of the bug spray: the small puddles can inflict gradual damage as you traverse the maze. Below are step-by-step directions to guide you through the anthill and highlight some potential benefits, such as acquiring valuable roach parts:
- Begin your descent into the Anthill.
- Take the first left turn.
- Upon reaching an opening, turn right.
- Continue straight past a cockroach.
- Your next objective is a direct approach; keep moving forward.
- When you spot the second roach, you’ll know you’re in the right area.
You will need to act quickly to grab the disk, as lingering too long may initiate a confrontation with the lurking cockroach queen in this area. While she won’t attack immediately, it’s wise to be prepared for a battle if you delay your escape.
Additionally, a special weapon called Gloom Skewer can be found hidden behind some mushrooms in the same room. If you possess a level two axe, you can dismantle the mushrooms to acquire this powerful item.

This disk unlocks several valuable items, primarily focused on enhancing your base construction, which will prove crucial for defending against the Masked Strangers’ raids. Below is a list of the available items and their respective costs:
