What Lies Underground APK + MOD v1.3 (All Locations Unlocked, All Items Unlocked, In-App Purchases Free, Ads Disabled)

What Lies Underground Mod is a first-person puzzle adventure game developed by Positronic Studios Ltd. The player assumes the role of an amnesiac protagonist who must explore a series of underground locations to uncover the mystery of their situation. The core gameplay involves searching nearly 80 distinct scenes for hidden objects and solving environmental puzzles to progress. The app targets players of narrative-driven puzzle games with an emphasis on atmospheric exploration.

What This Mod Unlocks

• All 80+ locations are unlocked from the start, bypassing the sequential progression system.
• All inventory items required for puzzles are available without needing to find them.
• In-app purchases for unlocking areas and hints are free.
• Advertisements displayed between scenes or during gameplay are removed.

The modded version of What Lies Underground Mod grants immediate access to the full game world. This eliminates the primary monetization gate of the official release, which requires players to purchase access to later areas or use hints.

To access the unlocked content, simply launch What Lies Underground Mod after installation. The main map screen will display all locations as available, indicated by an unlocked icon state. No additional menu or activation button is required; the modifications are applied directly to the game's progression logic.

The mod requires Android 4.0 or higher. The installation file is approximately 93 MB. Additional storage will be used for save data. Root access is not required for installation or functionality.

Installation follows the standard sideload process for modified APK files. First, enable installation from unknown sources in your Android security settings. Second, download the What Lies Underground Mod mod APK file. Third, locate the downloaded file using a file manager and tap to install. Fourth, launch the game from your app drawer.

Several edge cases exist with this mod. The game's cloud save functionality, if any, may not synchronize unlocked progress with official servers. Clearing the app data will reset any puzzle progress but will not re-lock the locations—they remain accessible. On some devices with custom ROMs, the game's graphics may fail to load correctly if hardware acceleration is unsupported.
