The sightline system in Lurking Giants determines what the Giant can see during normal gameplay — outside of visibility pulse highlights. While the pulse forces periodic exposure, the sightline system governs the constant cat-and-mouse game between pulses. Understanding how line of sight works, what blocks it, and how different Giants interact with barriers is essential for choosing the right cover and knowing when you are truly hidden.
How Line of Sight Works in Lurking Giants
The Giant's normal vision follows a standard line-of-sight model. If there is an unobstructed path from the Giant's camera to your character, the Giant can see you. If a solid object blocks that path, the Giant cannot see you — unless they are using Haunt, which has different penetration rules.
The Three States of Visibility
Your visibility to the Giant falls into one of three states at any given time:
| State | When It Occurs | Can the Giant See You? | What to Do |
|---|---|---|---|
| Pulse Highlighted | During visibility pulse (~10 sec) | Yes — always, regardless of cover | Stay in cover, plan relocation |
| In Sightline | Giant has unobstructed view | Yes — normal vision | Break line of sight immediately |
| Concealed | Solid barrier between you and Giant | No — unless Haunt penetrates | Stay still, stay quiet |
The critical distinction is between "Concealed" and "In Sightline." Between pulses, the Giant relies entirely on normal sightline to find survivors. If you are behind a solid wall and not highlighted, you are invisible.
How to Break Line of Sight
Breaking line of sight means placing a solid barrier between yourself and the Giant. The most effective ways include:
- Move behind a wall: Any building wall, cave wall, or rock face completely blocks normal sightline.
- Enter a tunnel: Tunnels on the City map provide complete concealment from external sightlines.
- Use vertical elevation: Rooftops can break ground-level sightlines, but be aware that the Giant can look up.
Important: Bushes and foliage do NOT break line of sight. They provide visual camouflage but the Giant can still see your character model through bush cover. Bushes only reduce your visibility at a distance — they are not reliable concealment.
Cover Effectiveness by Type
Not all cover is created equal. Different types of barriers block different amounts of Giant vision and abilities. This is the most important distinction to understand for intermediate play.
Cover Type Effectiveness Matrix
| Cover Type | Blocks Normal Sight | Blocks Locust Haunt | Blocks Guilt Haunt | Overall Rating |
|---|---|---|---|---|
| Bushes | Partially | No | No | Low |
| Building walls | Yes | Yes | No (penetrates) | High vs Locust only |
| Cave/rock walls | Yes | Yes | Partially (~60%) | High vs both |
| Tunnel ceilings | Yes | Yes | Significantly (~60%) | Very High |
| Rooftop elevation | Partially | Partially | No (penetrates floor) | Medium vs Locust |
| Interior building | Yes | Yes | No (penetrates) | High vs Locust only |
Why Guilt Haunt Penetrates Walls
Guilt's Haunt ability (G key) is a scanning pulse that penetrates most building walls. This is what makes Guilt the S-tier Giant — survivors cannot simply hide behind a wall and expect to be safe. Guilt's Haunt works like a sonar scan that reveals survivors through most barriers, though its effectiveness is reduced by cave walls and tunnel ceilings (approximately 60% reduction).
This means that against Guilt, the only truly reliable cover types are:
- Caves with thick rock walls — Reduce Haunt effectiveness by ~60%
- Deep tunnel networks — The tunnel ceiling significantly reduces Haunt penetration
- Cover combined with constant movement — Even if Haunt reveals you briefly, being on the move reduces the window for Guilt to act
Why Locust Haunt Does NOT Penetrate Walls
Locust's Haunt ability is a directional reveal that does NOT penetrate solid barriers. If you are behind a building wall, cave wall, or in a tunnel, Locust's Haunt cannot detect you. This is why Locust is rated B-tier — survivors can reliably counter Locust by staying behind solid walls.
Key tactical difference: Against Locust, solid walls are absolute protection. Against Guilt, solid walls are partial protection at best. Your cover choices must account for which Giant is active in the current round.
The Sightline Margin Concept
Sightline margin is the distance between your position and the nearest point where the Giant could establish line of sight. A larger margin means more reaction time if the Giant approaches.
Calculating Your Margin
| Position | Sightline Margin | Reaction Time | Risk Assessment |
|---|---|---|---|
| Center of cave | 10-15 meters | 4-6 seconds | Very Safe |
| Edge of building | 2-3 meters | under 1 second | Dangerous |
| Behind bush | 0-1 meter | under 0.5 seconds | Extremely Dangerous |
| Center of tunnel | 15+ meters | 5+ seconds | Very Safe |
| Edge of rooftop | 0 meters (exposed) | 0 seconds | Extreme Risk |
The rule: Always maximize your sightline margin. Position yourself in the deepest part of your cover, not at the edge. The deeper you are, the more time you have to react when the Giant approaches.
Lantern and Light Visibility
Your character's lantern in Lurking Giants is visible to the Giant at all times, even when you are concealed behind a wall. The light seeps through gaps and around corners, creating a glow that experienced Giants use to locate survivors even without line of sight.
Lantern Management Rules
- Turn off the lantern during inter-pulse periods — The default state should be lantern-off. Only turn it on briefly when navigating dark tunnels or caves.
- Never use the lantern on City map stairs — Stair gaps make light visible from multiple floors, alerting Guilt to your vertical position.
- The lantern does NOT help you see the Giant — It only illuminates your immediate surroundings. Rely on audio cues instead.
- Other survivors' lanterns can expose your position — If a nearby survivor has their lantern on, the Giant may investigate the area and find you too.
The Powerful Flashlight Advantage
The Powerful Flashlight game pass provides enhanced visibility without increasing your detection risk as much as the default lantern. However, it still produces visible light. Use it sparingly in the same situations where you would use the default lantern.
Audio vs Sightline: The Complete Detection Picture
The Giant has two detection methods: sightline (vision) and audio (sound). Understanding both is essential for true concealment.
Audio Detection
- Footsteps: Sprinting with E key produces audible footsteps. Walking is nearly silent.
- Lantern sound: Toggling the lantern on/off produces a click sound.
- Haunt activation: The Giant's Haunt (G) produces a distinct audio cue that survivors can hear, giving advance warning.
- Proximity voice: Any voice chat in the Giant's proximity is audible.
Combining Sightline and Audio Concealment
| Action | Sightline Risk | Audio Risk | Combined Risk |
|---|---|---|---|
| Standing still in cave, lantern off | None | None | None — fully concealed |
| Walking to new cover | Low | Low | Low |
| Sprinting to new cover | Medium | Medium | Medium |
| Sprinting in open area | High | Medium | Very High |
| Lantern on in tunnel | Medium (light leak) | None | Medium |
The optimal state between pulses is: standing still in deep cover, lantern off, no movement, no voice. This provides zero sightline exposure and zero audio exposure.
Advanced Sightline Tactics
The "Corner Peek" Technique
When you need to observe the Giant's position without exposing yourself, use the "corner peek" technique:
- Position at the edge of a wall: Stand close enough to see past the corner
- Rotate camera to see around the corner: Use your mouse to look past the edge without moving your character
- Note the Giant's direction: Identify which way the Giant is moving
- Retreat immediately: Do not linger at the corner — pull back to deep cover
This technique works on both maps but is especially useful on City, where building corners create natural peek positions.
The "False Lantern" Decoy
If the Giant is approaching and you need to misdirect them, the lantern can be used as a decoy:
- Turn your lantern on briefly (1-2 seconds) at one position
- Turn it off immediately and sprint in a different direction
- The Giant sees the light and may investigate that position
- You are already gone when the Giant arrives
| Decoy Effectiveness | Against Locust | Against Guilt |
|---|---|---|
| Forest cave entrance | Medium — Locust may investigate | Low — Guilt uses Haunt to scan area |
| City building corner | Medium — Locust follows light visually | Low-Medium — Guilt may Haunt the area |
| Open area | Low — too dangerous to linger | Very Low — Guilt will Haunt before chasing |
The "Parallel Cover" Strategy
When relocating after a pulse, always move to cover that is parallel to the Giant's approach direction, not perpendicular:
- Perpendicular movement (directly away from the Giant): You move in a straight line that the Giant can follow
- Parallel movement (sideways relative to the Giant): You move laterally, forcing the Giant to change direction
| Movement Type | Giant Tracking Difficulty | Survivor Safety | Best For |
|---|---|---|---|
| Direct retreat (away) | Easy — straight line | Low | Emergency escapes only |
| Lateral movement (sideways) | Medium — requires direction change | Medium | Most relocation scenarios |
| Diagonal movement | Hard — unpredictable vector | High | Skilled survivor play |
Post-Pulse Sightline Recovery
After a visibility pulse, the most dangerous period is the 10-15 seconds when the Giant is heading toward your revealed position. During this period, you must break line of sight as quickly as possible:
- Immediately after highlight fades: Sprint laterally (not directly away) to break the Giant's visual tracking
- Within 5 seconds: Enter solid cover (wall, cave, tunnel) that blocks normal line of sight
- Within 10 seconds: Be stationary in deep cover with lantern off
The key insight is that breaking the Giant's visual lock is more important than distance. A survivor who runs 30 meters in the Giant's line of sight is easier to track than a survivor who runs 10 meters behind a wall.
Frequently Asked Questions
Can the Giant see through walls? Not with normal vision. However, Guilt's Haunt ability (G key) penetrates most building walls and reveals survivors behind them. Locust's Haunt does NOT penetrate walls. Caves and tunnels reduce both Giants' Haunt effectiveness by approximately 60%.
Do bushes hide me from the Giant? Partially. Bushes provide visual camouflage but do not fully block line of sight. The Giant can still see your character through bush cover, especially at close range. Bushes are low-reliability concealment.
Should I ever use my lantern? Sparingly, and only in deep cover where the light cannot leak to exposed areas. Turn it on briefly to navigate, then turn it off immediately. Never use it on City map stairs or near stair gaps.
What is sightline margin? It is the distance between your position and the nearest point where the Giant could see you. A larger margin gives you more reaction time. Always position yourself in the deepest part of your cover, not at the edge.
How do I know if the Giant is using Haunt? You will hear a distinct audio cue when the Giant activates Haunt (G). This gives you 2-3 seconds of advance warning. If you hear Haunt and you are behind a building wall (against Guilt), start moving to cave or tunnel cover immediately.
