Oxenfree: Investigate the Military Base. Solve radio puzzles, find audio logs, and reach the Communications Tower using precise frequencies.
Following your unsettling discoveries at the Adler Estate, your journey continues westward towards the ominous Military Base Entrance. This section of Edwards Island presents a significant shift in gameplay, introducing more complex environmental puzzles that demand keen observation and precise radio manipulation. The atmosphere here is heavy with the echoes of past experiments and forgotten secrets.
Navigating to the Military Base
The path to the Military Base is linear but punctuated by obstacles. Keep your radio handy and your eyes peeled for visual cues. As you approach the main gate, you'll encounter your first major radio-based puzzle.
- Military Base Gate Puzzle: To open the initial gate, you'll need to tune your radio to a specific frequency. Listen for the distinct, rhythmic static that indicates a frequency related to a mechanism. The correct frequency for the main gate is typically around 104.7 MHz. Hold the frequency steady until the gate fully retracts.
Once inside the perimeter, the path will lead you through dilapidated barracks and overgrown research facilities. The air grows colder, and the whispers of the island's past become more pronounced.
Exploring the Abandoned Facilities
The Military Base is a labyrinth of interconnected structures, each holding clues to the island's dark history. Your primary objective here is to locate the Communications Tower, but a thorough exploration will reward you with invaluable lore and progress the narrative significantly.
Key Locations and Puzzles within the Base:
- Barracks A (First Building on Left):
- Radio Puzzle - Locked Door: Inside Barracks A, you'll find a locked door blocking access to a small office. To open it, you'll need to find a frequency that resonates with the old electronic lock. Scan the dial carefully; the frequency is often around 98.1 MHz. Holding this frequency will unlock the door.
- Collectible - Audio Log (Barracks Log 1): Inside the unlocked office, on a dusty desk, you'll find an old reel-to-reel tape player. Interact with it to play Audio Log #3: "Project Echo - Initial Findings." This log details the early, unsettling results of the military's experiments with dimensional rifts and resonance.
- Research Lab (Central Building):
- Environmental Puzzle - Power Conduit: The main research lab is dark. To proceed, you'll need to restore power. Locate a flickering power conduit on the wall. Tune your radio to a frequency that stabilizes the conduit's energy flow. This frequency is usually around 102.3 MHz. Maintaining this frequency will illuminate the lab.
- Collectible - Audio Log (Research Log 1): Once the power is restored, a console in the center of the lab becomes active. Interact with it to play Audio Log #4: "The Anomalies of Edwards Island." This log provides crucial information about the entities' nature, their connection to specific frequencies, and the military's attempts to weaponize them. This is a particularly important lore piece.
- Collectible - Message in a Bottle: Near a broken window in the research lab, you might spot a glint. Interact with it to pick up Message in a Bottle #2, offering a cryptic personal account from a former base resident.
- Storage Depot (Rear Building):
- Radio Puzzle - Automated Crane: To clear a path through the storage depot, you'll need to activate an old automated crane. The control panel is broken, but your radio can override it. The frequency to activate the crane and move the obstructing crates is typically around 106.9 MHz. Hold it until the path is clear.
- Collectible - Audio Log (Storage Log 1): On a shelf near the crane controls, you'll find another tape player. This contains Audio Log #5: "Evacuation Order." This log details the chaotic final moments of the base's abandonment, hinting at a sudden and violent incident.

Reaching the Communications Tower
After navigating the various facilities, your path will converge towards the imposing Communications Tower, visible in the distance. As you approach, the radio static will intensify, indicating a strong presence of the entities.
- Communications Tower Access: The final approach to the tower is often guarded by a locked gate or a malfunctioning elevator. The frequency to bypass this final obstacle is usually around 108.0 MHz. This frequency is particularly volatile and may require more precise tuning and holding.
Upon reaching the Communications Tower, a significant narrative event will trigger. Prepare for a tense encounter and revelations that will deepen your understanding of the island's supernatural phenomena and your role within it. The tower acts as a focal point for the entities' influence, and your interaction here will have lasting consequences.
Important Considerations and Tips:
- Radio Sensitivity: The radio puzzles in the Military Base often require more precise tuning than earlier sections. Listen carefully for the distinct sounds associated with each mechanism – a steady hum, a rhythmic pulse, or a high-pitched whine.
- Environmental Clues: Always look for visual cues. Flickering lights, sparking wires, or subtle shifts in the environment often indicate a nearby radio puzzle or an interactable object.
- Dialogue Choices: Your conversations with Ren, Nona, Jonas, and Clarissa continue to shape your relationships. Pay attention to their reactions, especially during the more unsettling discoveries within the base.
- Missable Lore: The audio logs and messages in a bottle are easily missed if you rush through the area. Take your time to explore every room and interact with all glowing objects. These provide critical backstory and context for the game's events.
The Military Base is a pivotal location in Oxenfree, rich with lore and challenging puzzles. A thorough investigation will not only advance the plot but also provide a deeper, more unsettling understanding of Edwards Island's dark secrets.
