The Alien Invasion Update in 99 Nights in the Forest has transformed the survival experience with UFO crashes, alien technology, and access to the mysterious mothership. This comprehensive guide will teach you everything about finding UFO crash sites, defeating alien invaders, and successfully infiltrating the alien mothership for incredible rewards.

UFO crashes occur randomly after Night 3 when you see “something mysterious is flying above you.” Look for yellow-glowing saucers with teleporters to access the mothership, where you’ll face challenging combat but earn exclusive alien weapons like Ray Guns and Laser Swords.

Understanding the Alien Invasion Event

When UFO Crashes Occur?

The alien invasion mechanics begin early in your survival journey. Upon entering the forest after the Alien Update, you’ll notice a holographic message stating “backup on its way.” This sets the stage for what’s coming.

Timeline of Events:

Night 1-2: Initial holographic warnings appear
Night 3+: “Something mysterious is flying above you” triggers
End of Night: Red outlines appear followed by crash sounds
Next Morning: Saucer icons visible on your map

Reading the Signs

Watch for these critical indicators:

Flying Saucers: Small objects darting across the night sky
Red Outlines: Appear just before crashes occur
Crash Sounds: Loud impact noises signaling successful landings
Map Icons: Saucer symbols showing exact crash locations

The key difference from regular forest threats is that alien events are time-sensitive. Other players can loot crash sites, so speed is essential for securing the best alien technology.

How to Find UFO Crash Sites in 99 Nights in The Forest?

Step 1: Prepare for Alien Nights

Before UFO events trigger, ensure you’re ready:

Essential Preparation:

Craft a Map (3 Wood Logs) – absolutely critical for navigation
Stockpile food and healing items
Gather ammunition for your weapons
Coordinate with teammates if playing in groups

Pro Tip: The Map is your most important tool. Without it, you won’t see crash site markers and will miss valuable opportunities.

Step 2: Track Flying Objects

During nighttime, actively scan the skies. UFOs appear as small, fast-moving objects that streak across your field of vision. They’re easier to spot in open areas away from dense tree cover.

Best Viewing Positions:

Open clearings and meadows
Elevated terrain near your base
Areas with minimal tree obstruction
Base rooftops if you’ve built upward

Step 3: Navigate to Crash Sites

Once you hear crash sounds and see red outlines, immediately check your map. Saucer icons will appear showing exact crash locations.

Navigation Strategy:

Open your map immediately after crashes
Note multiple crash sites (usually 3-5 per event)
Plan an efficient route between sites
Prioritize closer locations first

Step 4: Identify the Mothership Portal

Among the various crash sites, one will glow distinctly yellow. This is your ticket to the mothership. The yellow-glowing saucer contains a functional teleporter that transports you to the alien vessel.

Identifying Features:

Bright yellow illumination (much brighter than other crashes)
Intact teleporter door
Usually guarded by stronger alien enemies
Contains the most valuable preliminary loot

Surviving UFO Crash Site Combat

Enemy Types and Threats

Crash sites are heavily defended by alien forces. Understanding enemy behavior is crucial for survival.

Alien Enemy Variants:

Standard Aliens: Basic ground troops with energy weapons
Alien Elites: Stronger variants with advanced equipment
Flying Units: Aerial threats that require ranged combat
Protective Shields: Some aliens have temporary invulnerability

Combat Strategies

Recommended Loadout:

Primary Weapon: High-damage ranged weapon (preferably Ray Gun if obtained)
Secondary: Backup firearm with plenty of ammunition
Healing Items: Bandages, food, medical supplies
Lighting: Flashlight for visibility during night combat

Tactical Approach:

Survey Before Engaging: Observe enemy positions from distance
Use Cover: Trees, rocks, and terrain for protection
Focus Fire: Eliminate Alien Elites first
Manage Ammunition: Conservation is key for sustained fights
Retreat Option: Always have an escape route planned

Looting Crash Sites

After clearing enemies, systematic looting maximizes your rewards:

Priority Loot Order:

Alien Weapons (Ray Gun, Laser Sword, Laser Cannon)
Blueprints (Laser Fence and other schematics)
UFO Components (crafting materials)
Alien Devices (special equipment)
Standard Resources (scrap, materials)

Storage Management:

Empty inventory space before visiting crash sites
Prioritize unique alien items over standard materials
Share loot with teammates for balanced loadouts

Accessing the Alien Mothership in 99 Nights in The Forest

Finding the Yellow-Glowing Saucer

The mothership access point is always the yellow-glowing UFO. This crash site differs significantly from others:

Distinctive Characteristics:

Intense Yellow Glow: Visible from significant distances
Intact Structure: Less damaged than other crash sites
Functional Technology: Active teleporter systems
Heavy Defense: Multiple Alien Elite guards

Pre-Mothership Preparation

Before entering the mothership, complete these essential preparations:

Mandatory Equipment:

Ray Gun: Absolutely critical for mothership combat
Maximum Ammunition: Collect from all crash sites
Full Health/Food: Start at peak condition
Backup Weapons: Secondary firearms as fallback

Team Coordination:

Assign roles (combat, support, looting)
Establish communication protocols
Plan loot distribution in advance
Designate emergency retreat signals

Using the Teleporter

At the yellow-glowing saucer, locate the teleporter door. It appears as a glowing portal with alien technology surrounding it.

Activation Process:

Clear all defending aliens around the saucer
Approach the teleporter entrance
Interact with the portal (usually automatic)
Prepare for immediate combat upon arrival

What to Expect:

Instant transportation to mothership interior
Immediate alien resistance
Limited escape options once inside
Progressive difficulty as you advance

Navigating the Alien Mothership

Mothership Layout and Structure

The alien mothership functions as a combat gauntlet similar to Cultist Strongholds but with unique alien technology and layout.

Key Areas:

Entry Chamber: Initial teleporter arrival point
Security Corridors: Multiple branching pathways
Combat Zones: Large rooms with enemy waves
Restricted Doors: Captain-only access points
Central Core: Final area with greatest rewards

Understanding Door Restrictions

A major obstacle in the mothership is restricted access doors. These display notices stating access is limited to “Captains Only.”

Door Access Solution:

Defeat Alien Elites: Target these stronger enemies specifically
Collect Elite Bodies: Pick up defeated Alien Elite corpses
Position at Scanner: Place elite bodies next to door scanners
Automatic Unlock: Doors open when elite presence detected

Strategic Implications:

Don’t ignore Alien Elite enemies
Elite bodies are valuable resources
Some doors require multiple elite clearances
Plan your combat to secure necessary access

Combat in Confined Spaces

Mothership combat differs significantly from open-world forest fighting.

Environmental Challenges:

Narrow Corridors: Limited movement and cover options
Close Quarters: Enemies engage at short range
Multiple Levels: Vertical combat elements
Energy Barriers: Alien technology blocking paths

Adapted Combat Strategies:

Ray Gun Superiority: Unlimited ammunition crucial in sustained fights
Corner Tactics: Use corridor intersections for cover
Retreating Combat: Fall back to previous rooms when overwhelmed
Resource Conservation: Minimize waste of limited supplies

Frequently Asked Questions

How often do UFO crashes occur?

Can I solo the alien mothership?

While challenging, soloing the mothership is possible with proper preparation. You’ll need a Ray Gun, maximum ammunition, full health, and excellent combat skills. The Alien or Cyborg class significantly improves your solo chances.

What happens if I die in the mothership?

Death in the mothership functions like other areas – you’ll lose your items and respawn at your base. However, the mothership may reset, requiring you to wait for another yellow-glowing saucer event to retry.

Are alien weapons permanent?

Yes, alien weapons like the Ray Gun and Laser Sword persist across sessions like other equipment. They’re valuable permanent additions to your arsenal that dramatically improve your survival capabilities.
