Who is Guest 666?

Guest 666 is one of the most formidable enemies introduced in the Deadly Delivery Forest Update. This massive entity serves as the primary obstacle in the Underground Forest, making your food delivery missions significantly more challenging. What makes Guest 666 particularly terrifying is its relentless pursuit and devastating damage output.

Unlike other entities you’ve encountered in previous floors, Guest 666 operates differently:

Exclusive to Underground Forest: You won’t find this beast anywhere else in the game
Giant Size: Its massive bulk prevents it from entering houses or elevators, which is actually a key advantage for players
High Damage: Each hit from Guest 666 can be devastating, making avoidance crucial
Persistent Pursuit: Once it spots you, it won’t give up easily

Prerequisites: What You Need Before Facing Guest 666?

Before you even think about taking on this monster, you need to be properly prepared. Here’s what I recommend having in your arsenal:

Essential Items

Bat: Your primary weapon for this strategy
Ray Gun: Crucial for enlarging your bat
Stamina Items: You’ll be doing a lot of running
Health Items: Mistakes happen, be prepared
Teammates Who Listen: This is non-negotiable

Recommended Classes

While any class can technically attempt this fight, some are better suited than others:

Escape Artist: The stamina regeneration and movement speed bonuses are invaluable
Scout: Enhanced mobility helps with kiting
Tank Classes: If you prefer a more defensive approach

Floor Progression

Remember, Guest 666 only appears in the Underground Forest, which means you need to survive until floor 18. The floor progression looks like this:

Floors 1-3: The Surface
Floors 4-10: The Industrial level
Floors 11-17: The Deep level
Floors 18-30: The Underground Forest (Guest 666 territory)

The Ultimate Strategy: Step-by-Step Guide to Defeating Guest 666

After analyzing multiple strategies and testing different approaches, I’ve found what works consistently. This method combines preparation, positioning, and execution to give you the best chance of victory.

Step 1: Prepare Your Bat

Start by equipping your bat. This isn’t just any weapon choice – it’s the foundation of our entire strategy. The bat provides the perfect balance of reach and safety, allowing you to attack while maintaining some distance from Guest 666.

Why the bat works best:

Good reach for keeping distance
Familiar attack pattern for most players
Effective when enlarged with the ray gun
Doesn’t require precise aiming under pressure

Step 2: Use the Ray Gun to Enlarge Your Bat

This is where the magic happens. Use your ray gun to enlarge the bat. A bigger weapon dramatically improves your effectiveness in several ways:

Benefits of an enlarged bat:

Increased Range: You can hit Guest 666 from farther away
Better Coverage: More area for hitting during the chase
Improved Safety: Greater distance between you and the monster
Visual Advantage: Easier to track your weapon position during intense moments

Step 3: Locate Guest 666

Once you’re properly equipped, it’s time to find your target. The Underground Forest is vast, so this might take some time. Here’s what to look for:

Guest 666 spawn indicators:

Unusually quiet areas (the calm before the storm)
Distanced from other entities
Near large open spaces
Close to house structures (important for our strategy)

Pro tip: Don’t attack immediately upon sighting. The goal is to lure Guest 666 to a favorable location, not engage in open combat.

Step 4: Find a Nearby House

This is arguably the most critical step in the entire strategy. You need to locate a house close to where you find Guest 666. The house isn’t just cover – it’s your primary tactical advantage.

What makes a good house for this strategy:

Proximity: Close enough to lure Guest 666 to it
Structure: Good for looping around without getting trapped
Space: Enough room to maneuver around the exterior
Isolation: Away from other threats and teammate interference

Step 5: Lure Guest 666 Outside the House

Now comes the delicate part. You need to bring Guest 666 near the house area, but you must keep the fight outside. Here’s how to do it effectively:

Luring technique:

Get Guest 666’s attention (a quick hit usually works)
Run toward the house you’ve selected
Position yourself so Guest 666 follows you to the exterior
Quickly enter the house once Guest 666 is positioned outside

Critical warning: Do NOT try to fight inside the house. The space is too tight, and you’ll get trapped. The house is for protection and positioning, not combat.

Step 6: Start Kiting Around the House

This is where the strategy comes together. You’ll use the house as a central point for kiting Guest 666 in circles.

Kiting mechanics:

Move around the house in consistent circles
Keep Guest 666 on the opposite side of the house from you
Use the house as a barrier between you and the monster
Attack with your enlarged bat when Guest 666 is within range
Maintain a steady rhythm – don’t rush or panic

Why this works:

Guest 666’s size prevents it from cutting corners effectively
The house provides consistent cover and predictable pathing
You control the pace and positioning of the fight
The enlarged bat gives you enough reach to hit safely

Step 7: Ensure No Teammates Interfere

This step is absolutely crucial and cannot be overstated. If teammates come too close, Guest 666 may switch targets and chase them instead, completely breaking the strategy.

Team management strategies:

Communicate clearly: Tell teammates exactly what you’re doing
Choose isolated houses: Pick locations away from busy areas
Use voice chat: If available, coordinate in real-time
Be prepared to restart: If teammates interfere, you may need to find a new location

What happens when teammates interfere:

Guest 666 changes targets unpredictably
The kiting pattern breaks down
You lose positional advantage
The fight becomes chaotic and dangerous

Step 8: Take Advantage of the Predictable Pattern

Here’s where things get interesting. Guest 666 sometimes gets stuck in a predictable pattern when circling the house. This might be a bug, but it’s currently working in players’ favor.

Pattern recognition:

Guest 666 may follow the same path repeatedly
The timing becomes consistent and predictable
You can anticipate movements and plan attacks
The fight becomes significantly easier once the pattern establishes

How to exploit this:

Observe Guest 666’s movement for a few loops
Time your attacks to coincide with predictable positions
Maintain your kiting rhythm even when the pattern is obvious
Be prepared for potential pattern changes (bugs can be fixed)

Advanced Tips and Pro Strategies

Once you’ve mastered the basic strategy, you can incorporate these advanced techniques to improve your success rate even further.

Weapon Optimization

While the bat + ray gun combo is the most reliable, other weapons can work in specific situations:

Alternative weapon setups:

Stun Grenade + Bat: Use stun grenades to create openings for bat attacks
Random Teleporter: Emergency escape if positioning goes wrong
Heavy Weapons: If you have a team that can tank hits

Movement Mastery

Your movement is just as important as your weapon choice:

Advanced movement techniques:

Stamina Management: Know when to sprint and when to conserve energy
Corner Cutting: Use slight shortcuts while maintaining the kiting pattern
Positional Awareness: Always know where Guest 666 is relative to the house
Escape Routes: Plan multiple ways to disengage if needed

Team Coordination

If you’re playing with a team, coordination becomes even more critical:

Team-based strategies:

Designated Kiter: One player focuses entirely on kiting Guest 666
Support Players: Teammates handle other threats and provide backup
Distraction Tactics: Use noise or movement to control Guest 666’s attention
Revive Support: Have players ready to revive if someone goes down

Common Mistakes to Avoid

After watching countless attempts and analyzing failed runs, I’ve identified the most common mistakes players make when facing Guest 666.

Critical Errors

Fighting in Tight Spaces: Never engage in cramped areas
Ignoring Teammate Positioning: Uncontrolled teammates ruin the strategy
Poor Weapon Choice: Using weapons that don’t complement the kiting style
Impatience: Rushing the fight leads to mistakes
No Escape Plan: Always have a way to disengage if things go wrong

Tactical Mistakes

Breaking the Kiting Pattern: Consistency is key
Poor House Selection: Not all houses work equally well
Inadequate Preparation: Entering the fight under-equipped
Misjudging Distance: Getting too close to Guest 666
Ignoring Stamina: Running out of energy mid-fight is fatal

Platform-Specific Considerations

Different platforms may require slight adjustments to the strategy:

PC/Mouse and Keyboard

Advantage: Precise aiming and movement control
Consideration: Easier to maintain precise kiting patterns
Tip: Use mouse sensitivity settings to your advantage

Mobile/Touch Controls

Challenge: Less precise movement and aiming
Adaptation: May need to use larger houses for more margin of error
Tip: Practice movement patterns in safer areas first

Controller

Balance: Good movement but potentially less precise aiming
Strategy: May benefit from aim assist settings if available
Tip: Customize controller layout for quick access to essential items

FAQ

How long does it take to defeat Guest 666?

The fight duration varies depending on your weapon upgrades and skill level, but typically takes 3-5 minutes once you establish the kiting pattern. Some players report longer fights if they’re being extra cautious.

Can you defeat Guest 666 solo?

Yes, it’s absolutely possible to defeat Guest 666 solo. In fact, many players prefer solo runs because they eliminate the risk of teammate interference. The strategy remains the same, but you have complete control over the situation.

What happens if Guest 666 gets stuck?

If Guest 666 gets stuck in geometry or behaves unusually, you have a few options:

Continue attacking if it’s still vulnerable
Reset the encounter by moving away and returning
Report the bug if it’s preventing completion
Take advantage of the situation if it’s working in your favor

Is Guest 666 worth fighting for loot?

Currently, Guest 666 doesn’t drop any loot or rewards. However, defeating it is necessary for progression in the Underground Forest, and future updates may add loot drops. The satisfaction of victory is its own reward!

What’s the best class for fighting Guest 666?

The Escape Artist class is highly recommended due to its stamina regeneration and movement speed bonuses. However, any class can work if you master the kiting strategy. Choose a class that matches your playstyle and complements your team composition.

Can you use other weapons besides the bat?

While the bat + ray gun combo is the most reliable, other weapons can work. Stun grenades can create openings, and heavy weapons can deal more damage if you have a team that can tank hits. However, the bat’s balance of reach and safety makes it ideal for the kiting strategy.

What if there are no houses nearby?

If you can’t find a suitable house, look for other large structures that can serve the same purpose. The key is finding something large enough that Guest 666 can’t enter but you can use for cover and kiting. In worst-case scenarios, you may need to lure Guest 666 to a different area.

How often does Guest 666 spawn?

Guest 666 appears consistently in the Underground Forest (floors 18-30). You’re guaranteed to encounter it if you progress far enough, though the exact spawn location and timing can vary between runs.
