- Inspect Trunk: A core mechanic to detect hidden contraband in vehicles.
- Visual Cues: Look for inconsistencies in vehicle models and nervous driver behavior.
- Protocol: Always verify documentation against the physical vehicle condition.
- Tools: Use flashlights and scanners to reveal hidden compartments in the trunk.
- Efficiency: Balance thorough searches with keeping the border line moving.
Understanding Inspection Protocols
In Protect the Border, the ability to effectively inspect a trunk is the primary defense against smuggling. This mechanic is not just about opening the back of a car; it involves a systematic check of the vehicle's structural integrity, documentation matching, and behavioral analysis of the driver.
Video Highlights:
- Real-world border agents discuss the limitations of physical barriers.
- The importance of technology (cameras, sensors) over simple walls.
- How smugglers attempt to bypass "steel fences" and inspections.
While the video above discusses the geopolitical concept of border walls, in the context of the game, it highlights a crucial gameplay element: physical barriers alone are insufficient. You must rely on your inspection skills to catch what the fence stops. A trunk inspection is triggered when a vehicle reaches your booth. You must decide based on initial intel whether a standard check or a deep trunk inspection is required.
Do not inspect every single vehicle trunk unless you have a specific reason. Unnecessary inspections slow down the queue, potentially letting high-profile threats slip through while you are busy with a civilian car.
Step-by-Step Trunk Inspection
Performing a correct inspection follows a strict loop. Missing a step can result in contraband entering the country or innocent travelers being wrongfully detained, both of which negatively impact your score.
Document Verification
Before approaching the vehicle, check the driver's passport and vehicle registration. Ensure the photo matches the face and the license plate matches the registration document. Any discrepancy here warrants an immediate trunk inspection.
Visual Scan
Look at the vehicle's exterior. Does the model listed on the paper match the car? Are there suspicious modifications like reinforced bumpers or dark tint? These are visual cues that the trunk might be hiding something.
The Open Command
Click or tap the trunk area to issue the "Open Trunk" command. The driver will react. Watch their reaction animation closely—a nervous glance or a delay might indicate guilt.
Internal Search
Once open, use your cursor to scan the interior. Move loose items (spare tires, toolboxes) to see behind them. Look for false floors or taped packages.
Decision & Action
If the trunk is clean, stamp the document "APPROVED". If you find illegal items, stamp "DENIED" or trigger the alarm to dispatch agents to the scene.
Some advanced smuggling attempts use "ghost" compartments. If the trunk looks empty but the driver's stress level is high, use your scanner tool (if unlocked) to check for organic material behind the metal shell.
Identifying Contraband Types
Not every illegal item looks the same. Knowing what to look for speeds up the inspection process significantly. The game categorizes contraband into specific types, each hidden differently within the trunk.
| Contraband Type | Visual Clues | Common Hiding Spots |
|---|---|---|
| Narcotics | Small packages, taped bricks, vacuum-sealed bags | Behind side panels, under spare tire, inside speaker boxes |
| Weapons | Heavy shapes, metal parts, gun oil stains | Under the floor mat, inside hollowed-out jack compartments |
| Alien Artifacts | Glowing objects, strange geometric shapes | Inside the engine block (rare), inside spare tire well |
| Unauthorized Persons | Breathing movement, muffled sounds | Large hidden compartments, under a pile of blankets |
Narcotics
- High Value: High reward for seizure
- Small Size: Easy to hide
- Frequency: Common in sedans
Weapons
- Threat Level: Dangerous if missed
- Weight: Affects vehicle suspension
- Frequency: Common in trucks/vans
Stolen Goods
- Variety: Electronics, jewelry
- Packaging: Often in generic boxes
- Frequency: Random events
Advanced Search Techniques
As you progress in Protect the Border, simple visual checks become insufficient. You will unlock advanced tools that allow you to inspect trunks without opening them or see inside solid objects.
Unlocking the X-Ray Scanner (Level 10) allows you to peer through the metal sheet of the trunk. This is essential for detecting "steel fence" style modifications where smugglers weld boxes shut.
Comparing Inspection Methods:
| Method | Speed | Accuracy | Risk |
|---|---|---|---|
| Visual Only | Fast | Low | High miss rate on hidden items |
| Physical Search | Slow | High | Driver may get impatient/flee |
| X-Ray Scanner | Medium | Very High | Uses energy/battery resources |
| Sniffer Dog | Medium | High (Organic) | Dog requires cooldown time |
Using the Sniffer Dog is a passive way to inspect trunks. If the dog barks at the trunk, you know immediately to prioritize that vehicle. However, relying solely on the dog can be risky as smugglers may use scent-maskers.
Efficiency & Daily Goals
Balancing security with speed is the ultimate challenge. You cannot spend 10 minutes inspecting a single trunk when the queue is 20 cars deep. You need a strategy for triage.
Daily Inspection Goals:
- Successfully identify 5 hidden weapon stashes in trunks
- Maintain a queue wait time under 3 minutes
- Achieve 'Perfect Inspection' rating (no false positives)
- Unlock the Thermal Scanner upgrade
- Process 50 vehicles without a single contraband slip
If a vehicle has valid "Fast Track" paperwork, you can skip the trunk inspection unless the scanner alerts you. Use this to clear the backlog of civilian traffic so you can focus on suspicious vehicles.
Frequently Asked Questions
Q: What happens if I miss contraband in the trunk?
If you fail to detect illegal items and stamp 'APPROVED', you receive a penalty to your security score. Repeated failures can lead to a Game Over or demotion to a less secure border post.
Q: Can a driver refuse to open the trunk?
Yes, in some scenarios. If a driver refuses, you must immediately flag them as 'Suspicious'. Refusal is an automatic fail condition for the inspection, granting you probable cause to call for backup.
Q: How do I inspect the trunk if the car is full of luggage?
You must manually click and drag items out of the way. The game physics allow you to move suitcases and boxes. Check underneath and behind large items, as smugglers often hide small packets in blind spots.
Q: Is inspecting the trunk required for every vehicle?
No. Only inspect the trunk if the documentation is suspicious, the vehicle model triggers an alert, or the driver acts nervous. Inspecting everyone takes too long and will hurt your efficiency score.
