This complete 007 First Light mission walkthrough provides the most efficient stealth route through the 'First Light' operation at the Astra-Sol facility in Chile. The primary objectives are to retrieve the 'Helios' schematics from the central server and sabotage the primary solar collector before exfiltrating. Following these steps will ensure maximum stealth rating and unlock the "Clean Sweep" achievement.
Your goal is to infiltrate, acquire the data, disable the asset, and get out without raising a full-scale alarm. While the facility can be assaulted head-on, this guide focuses on the ghost approach, using gadgets and timing to leave your enemies wondering if you were ever there at all.
Recommended Loadout & Gadgets
Before starting, your loadout is critical for a non-lethal, stealth-focused run. While you can choose louder options, this selection is optimized for the challenges inside the Astra-Sol complex. Deviating from it may require you to improvise more during combat, which can compromise your mission rating.
- Primary Weapon: Silenced P99: The classic Bond sidearm, suppressed for quiet takedowns on cameras and essential guard patrols. A headshot is silent, but a missed shot is not.
- Gadget 1: EMP Watch: The single most important gadget for this mission. It has three charges and can temporarily disable electronic systems like cameras, laser grids, and server security panels from a distance. Its range is limited to about 10 meters.
- Gadget 2: Stun Pen: Your primary tool for non-lethal takedowns. It has a single charge that recharges every 45 seconds. Use it on guards you absolutely cannot sneak past. A stunned guard will remain unconscious for five minutes.
Phase 1: Infiltrating the Astra-Sol Perimeter
The mission begins at dusk, 500 meters from the facility's outer fence. The desert provides ample cover, but the real challenge is the layered electronic security.
Bypassing the Electric Fence
From your starting position, move northeast towards the fence line. You will see a small security checkpoint with two guards. Ignore it. Instead, follow the fence to the right (east) for about 100 meters until you find a junction box. Use your EMP Watch on the box. This disables a 20-meter section of the fence for 60 seconds, allowing you to climb over it undetected. Do not try to cut the fence, as this will trigger a silent alarm in the main security hub.
Neutralizing the Watchtowers
Once inside, you'll be in a large courtyard with two watchtowers, each manned by a single sniper. Taking them out is essential. The west tower guard has a predictable patrol pattern. Wait for him to face away from you, climb the ladder, and use the Stun Pen. The east tower guard is stationary. Use the Silenced P99 to shoot out the spotlight next to him; when he moves to investigate the sound, sneak up and neutralize him. This prevents them from spotting you as you cross the open ground toward the main building.
Finding the Maintenance Tunnel Entrance
The main entrance is a death trap. Instead, head for the large ventilation units on the northwest side of the central building. Behind a stack of crates, you'll find a locked grate leading to an underground maintenance tunnel. The lock is a simple tumbler minigame. Solving it grants you access to the building's lower levels, completely bypassing the lobby patrols.
Phase 2: Breaching the Central Data Hub
The tunnels will lead you to the sub-level of the Research Wing. From here, you need to access the heavily guarded server room on the floor above.
Navigating the Laser Grid Hallway
The corridor leading to the data hub is protected by a shifting grid of security lasers. There is a security camera at the far end of the hall. Use your EMP Watch on the camera first. This gives you a 15-second window where the laser grid shifts to a simpler, slower pattern. Sprint down the right side of the hallway, timing your movements with the two vertical beams. A hidden alcove on the right wall contains a security panel that will disable the lasers permanently.

Cracking the Server Room Keypad
The server room door has a sophisticated keypad lock. You cannot bypass it with gadgets. The code is held by the lead technician, who is in the adjacent server maintenance room. You can either knock him out and take his keycard, or you can sneak up to the glass partition and use your camera's zoom function to read the code off the sticky note on his monitor. The code is always a randomized 6-digit number. Entering the code grants you access without alerting any guards.
Downloading the Helios Schematics
Inside the data hub, access the central server. The download will take 90 seconds. During this time, a security patrol will enter the outer hallway. You must hide. The best spot is on top of the server racks to the left of the entrance. Wait for the guard to perform his check and leave before dropping down. Once the download is complete, grab the datastick. This completes your primary objective.
All 3 Secondary Intel Locations (Optional Objective)
For a 100% mission score, you must retrieve three optional pieces of intel. These provide more context on Dr. Thorne's plan and unlock bonus lore.

| Intel Piece | Location & Details | Optimal Gadget |
|---|---|---|
| Thorne's Comms Log | Research Wing, Dr. Thorne's office. The log is inside a wall safe behind a painting. The code (7309) is found on a PDA on his desk. | Stun Pen (for the single patrolling scientist) |
| Collector Power Specs | Engineering Deck, main control room. This area has two guards. The specs are on a laptop on the central console. | EMP Watch (to disable the security camera) |
| Escape Route Map | Security Barracks, locker #7. This is the most dangerous area, with four guards on patrol. The map is inside the only unlocked locker. | Distraction (shoot a non-essential screen) |
Acquiring all three without raising an alarm is the mission's hardest challenge and key to the "Master Spy" achievement.
Phase 3: Confronting Dr. Thorne
With the schematics secured, Moneypenny will direct you to the rooftop observatory to confront the facility's director, Dr. Aris Thorne.
The Rooftop Observatory
Take the service elevator near the Engineering Deck to reach the roof. Dr. Thorne is waiting for you, but he's not alone. This triggers a cutscene where he reveals his plan to use the solar collector as a weapon, followed by a boss encounter.
Boss Fight: Silas "The Ghost" Vance
Thorne's head of security, Silas Vance, engages you in combat. He is immune to direct frontal attacks and the Stun Pen. The key to this fight is using the environment. Vance is a stealth expert and will use smoke bombs to vanish and reappear.
- Break Line of Sight: Use the large telescope structure in the center of the roof to hide.
- Use Distractions: Throw objects to lure him to a specific spot.
- Perform Takedowns: When he is investigating a noise, sneak up behind him for a takedown. You must do this three times to defeat him.
Firing your P99 will only cause him to disarm you. This fight is a pure stealth challenge.
Phase 4: Sabotage and Exfiltration
After defeating Vance, a cutscene plays where you secure Dr. Thorne. Your final objective is to sabotage the massive solar collector and escape before MI6 calls in an airstrike.
Planting the Demolition Charges
You are given three demolition charges and a 90-second timer. You must plant them on the structural pylons that support the primary collector dish. The locations will be marked on your HUD. Two are on the main rooftop level, but the third requires you to slide down a maintenance ladder to a lower gantry. Guards will be on high alert, but you do not have time for stealth—sprint between the objectives.

The Escape to the Extraction Point
Once the last charge is set, a final 30-second timer begins. Your extraction point is a dune buggy at the far eastern edge of the facility perimeter. Sprint across the courtyard, ignoring any remaining guards. The charges will detonate as you jump into the driver's seat, triggering the final escape sequence. You will have to drive through the desert, dodging fire from enemy jeeps, to reach the exfiltration point and complete the mission.
Frequently Asked Questions (FAQ)
Can you complete the First Light mission without killing anyone? Yes. Using the Stun Pen for mandatory takedowns and sneaking past all other guards will award the "Agent of Mercy" achievement. The only exception is Silas Vance, who is subdued, not killed.
What's the code for Dr. Thorne's office safe? The code is always 7309. It can be found by reading the PDA on his office desk, but it never changes on subsequent playthroughs.
How do you get the "Solar Flare" achievement? This is awarded for planting all three demolition charges on the solar collector and reaching the dune buggy with more than 15 seconds left on the final escape timer.
Final Assessment
With the Helios schematics secured and Thorne's plan in ruins, the First Light mission is a success. This operation is a masterclass in level design, testing your ability to observe patterns, use your gadgets creatively, and execute with precision. It perfectly sets the stage for the global conspiracy that unfolds across the rest of the game.
