If you’ve made it to the Underground Forest in Deadly Delivery, you’ve probably encountered the nightmare that is Guest 666. This behemoth entity has been terrorizing players since the Forest Update dropped, and let me tell you – I’ve spent countless hours figuring out how to beat this guy. Today, I’m sharing everything I’ve learned about taking down Guest 666, from basic survival tactics to advanced strategies that actually work.
Guest 666 isn’t just another monster you can ignore or run past – this entity is the main boss of the Underground Forest, appearing exclusively on floors 18-30. What makes Guest 666 particularly terrifying is its combination of high damage output, relentless pursuit, and the fact that it’s a crossover entity from the game Forsaken, making it a unique challenge even for veteran players.
From my experience diving deep into the Underground Forest, Guest 666 operates differently from other entities. While most monsters have predictable patterns or specific weaknesses, Guest 666 is designed to be a persistent threat that forces you to use your environment and teamwork (or solo skills) to survive. The entity deals massive damage with each hit and can quickly end your run if you’re not prepared.
I’ll be honest – my first dozen encounters with Guest 666 were brutal. I’d get cornered, panicked, and end up losing all my hard-earned loot. But there’s something incredibly satisfying about finally figuring out the patterns and strategies that work against this massive foe. What I love most about the Guest 666 fight is how it forces you to master the game’s mechanics – you can’t just button-mash your way to victory.
The Underground Forest’s open design actually plays to your advantage once you understand how to use it. Unlike the cramped hallways of earlier floors, you have room to maneuver, kite, and plan your approach. After mastering Guest 666, I found myself becoming a better player overall, with improved map awareness and resource management skills.
Before you even think about engaging Guest 666, you need the right setup. Here’s what I’ve found works best:
Essential Gear:
Class Recommendations: Based on my testing, here are the best classes for facing Guest 666:

| Veteran | S-Tier | Balanced stats and extra health make mistakes less punishing |

This is the core method I’ve developed through trial and error, and it’s significantly more effective than the basic “run and hide” approach most guides suggest:

The Underground Forest is filled with opportunities to outsmart Guest 666:
Rushing the fight is the fastest way to lose. Here’s my recommended approach:
Make every item count:
Q: Can Guest 666 be killed permanently, or does it respawn? A: Guest 666 respawns after a short time if you move too far from its spawn area. However, defeating it gives you a temporary safe window to loot the area.
Q: What’s the minimum level/recommendations for attempting Guest 666? A: I recommend reaching at least floor 18 with a good understanding of basic game mechanics. Have at least 10,000 cash worth of gear and healing items.
Q: Do different weapons work better against Guest 666? A: The enlarged bat is consistently the best option due to its range and damage output. Other weapons either lack range or don’t deal enough damage to be worth the risk.
Q: Is Guest 666 easier with more players? A: Yes, significantly. With 3-4 players, you can have dedicated roles and much better control over the fight. However, it’s completely possible to beat solo with the right strategy.
Q: Are there any glitches or exploits that make fighting Guest 666 easier? A: While some players report pathing bugs where Guest 666 gets stuck on objects, I recommend learning legitimate strategies as these may be patched in future updates.
Mastering Guest 666 in Deadly Delivery isn’t just about memorizing patterns – it’s about understanding the game’s mechanics on a deeper level and developing the patience and skill to outthink this formidable foe. The strategies I’ve shared here have taken me from getting destroyed in seconds to confidently taking down Guest 666 consistently.
Remember, practice makes perfect. Don’t get discouraged if your first few attempts don’t go well. Each failure is a learning opportunity that brings you closer to mastering this challenging encounter. The Underground Forest holds some of the best loot in the game, and once you’ve conquered Guest 666, you’ll have access to rewards that make all the effort worthwhile.
Now it’s your turn! Grab your gear, round up your team (or go solo if you’re brave), and show Guest 666 who’s really in charge. I’d love to hear about your experiences and any additional strategies you discover in the comments below!
