Defend Your Base From 67 delivers pure adrenaline as you build, upgrade, and fiercely protect your base from the relentless 67 worm boss and its escalating waves. Developed by Simulator D2D and released in February 2026, this multiplayer survival game drops you into maps with unique environments where you claim a base, place defensive turrets and money-generating farms, and survive up to 67 intense waves. The hook? One wrong placement or missed repair, and the giant worm smashes through your door—game over. Yet every successful run rewards you with Gold, Gems, and the thrill of unlocking rarer, more powerful units that turn early struggles into late-game domination.
This guide walks you through every layer of the game. From your very first lobby spawn and base claim to mastering crate summons, optimal unit loadouts, and endgame scaling on harder maps, we cover the full journey. You’ll learn exact progression routes, crate drop rates, and pro-level resource balancing that separate casual defenders from those who crush Hard mode.
Whether you’re a total beginner dying on wave 10 or an experienced player chasing mythic towers and massive multipliers, this guide gives you actionable steps to survive longer, farm faster, and reach endgame power much quicker. Follow it, and you’ll avoid the common pitfalls that waste hours of progress.

Getting Started
Jump into the game and head straight to the lobby. Interact with the square teleporters to start or join a run—pick a map (Forest is the easiest starter), difficulty (Easy first), and player count. Once inside the map, quickly claim an available base by walking through its door. Each base has a fixed number of build spots and one critical door.
Your Money Printer auto-spawns in the center—upgrade it immediately for passive income. In the lobby before runs, use the Summon area and NPC to open crates with Gold or Gems you earn from previous games. You start with four free unit slots (a fifth costs Robux if you want it).
No active codes exist as of late March 2026, and there’s no redemption system yet—check the official group for future drops. Join the Simulator D2D community group right away for Season Pass EXP and extra rewards. First run? Play Easy on Forest, focus on door upgrades and basic turrets, and just survive as many waves as possible while dealing damage to the 67 boss for bonus Gold.
Progression & Leveling Roadmap
Progression revolves around completing runs to earn Gold and Gems, which unlock better crates, maps, and units. Start on Easy difficulty (typically ends around wave 20) to learn mechanics safely. Each full clear gives decent rewards and EXP toward the Season Pass.
Farm Gold by damaging the boss heavily—every hit counts toward crate currency. Use early Gold for Basic Crates to get starter units, then move to Legendary and Mythic as you scale. Unlock higher maps (Desert → Freezer → Lava) by spending Gems or beating prior stages. Harder difficulties and later maps have more waves and tougher boss attacks, but they offer bigger rewards and faster scaling.
Efficient roadmap:
- Waves 1–20 (Easy): Focus economy + basic DPS.
- Mid-game (after 5–10 clears): Unlock Legendary/Mythic crates and move to normal/hard modes.
- Endgame: Hard mode on Lava or advanced maps, full S-tier loadouts, and max door upgrades for boss-kill runs.
Re-run maps you’re comfortable with to stockpile resources before pushing new content.
Core Gameplay Mechanics
Your base has two pillars: defense and economy.
Door & Upgrades: The door is your lifeline. Upgrade it first every run—it boosts HP and unlocks better building options. When the 67 worm slams it, a repair button appears at the bottom of your screen—spam it during cooldown windows to stay alive.
Money Management: The auto-spawning Money Printer is your base income. Upgrade it relentlessly. Add money farms (Vault, Gold Mine, etc.) for passive Gold generation. Place farms spread out for efficiency.
Combat Units (Turrets): Place offensive turrets near the door for maximum DPS on the boss and waves. Units lock in place once deployed, so plan spots carefully. Upgrade them with available money (upward arrows show when ready). You can only equip four units (plus optional fifth). Focus on a mix of 2–3 high-DPS towers and 1–2 economy buildings.
Special Systems & Resources
Crates & Summoning (the heart of progression): Open these in the lobby to unlock new turrets and farms. Drop rates are fixed—here’s the breakdown:
| Crate Type | Cost | Key Drops & Rates |
|---|---|---|
| Basic Crate | 500 Gold | Vault (45%), Gun Turret (30%), Cannon (20%), Rock Catapult (5%) |
| Legendary Crate | 2,500 Gold | Cannon (50.5%), Gold Mine (33.9%), Oil Drill (14.1%), Flamethrower (1%), Ice Turret (0.5%) |
| Mythic Crate | 50 Gems | Oil Drill (59.9%), Minigun (25.5%), Diamond Mine (14%), Tesla (0.5%), Hacker (0.1%), Ray Gun (0.05%) |
| Galaxy Crate | ~120k–125k Gold (limited event, ended March 13, 2026) | Dragon Launcher (59.9%), Cactus Farm (25.5%), Lava Launcher (14%), Black Hole Generator (0.5%), Laser Cannon (0.1%) |
Gems also unlock maps and come from stage clears and badge achievements. Prioritize Mythic Crates once you have steady income—low-drop mythics like Tesla or Laser Cannon define endgame.
Maps, Stages, & Progression Unlocks
Four permanent maps with different visuals and slight difficulty tweaks:
- Forest (starter) – Easiest waves.
- Desert – Unlocks after Forest clears or Gems.
- Freezer – Colder environment, mid-tier challenge.
- Lava – Endgame favorite for high rewards.
Some runs mention a Galaxy map during limited events. Unlock maps with Gems or by beating previous ones on higher difficulties. Each map supports Easy, Normal, and Hard modes—Hard gives the best rewards but demands S-tier units and fast repairs.
Tips, Strategies & Best Practices
- Early runs: Door first, then Money Printer, then one economy building + basic turret. Place DPS near the door.
- Resource balancing: Never neglect economy—strong farms let you upgrade everything faster in later waves.
- Endgame meta: Run 3× S-tier DPS (Laser Cannon, Black Hole Generator, Tesla) + 1× top farm (Diamond Mine or legacy Cactus Farm). Stack door upgrades and repair on cooldown.
- Team play: Play with friends to cover more bases or share pressure on harder maps.
- Efficiency: Focus boss damage for extra Gold. Upgrade existing units before placing new ones. Avoid moving placed units—they’re permanent.
- Risk management: On Hard mode, save repairs for big slams and prioritize crowd-control units like Black Hole Generator for waves.
Events, Schedules & Special Spawns
The big limited event was the Galaxy Crate (ended March 13, 2026)—any players who opened it still have those powerful legacy units. Watch for admin events, double-reward weekends, or new crate drops via the in-game group or Discord. Rare mythic drops (Tesla, Hacker, Laser Cannon) feel like special spawns when they hit—farm Mythic Crates heavily when you can afford them. Season Pass tiers refresh with new units and multipliers; stay active in the community group for EXP.
Combat Paths / Styles / Masteries
This is pure tower defense—no player weapons or Haki-style systems. Your “style” comes from your unit loadout and placement. Beginners start with Gun Turret + Cannon for wave clear. Mid-game shifts to Flamethrower/Ice Turret for control. Endgame mastery is the mythic DPS stack: Laser Cannon for single-target boss melts, Black Hole Generator for AoE pulls, and Tesla for chain lightning. Master door repair timing and economy scaling—these separate good runs from record clears.
Frequently Asked Questions
How do I get better units fast?
Farm Gold by damaging the 67 boss heavily every run, then open Legendary/Mythic Crates in the lobby. Focus economy early so you can afford more summons.
What’s the best starter loadout?
Money Printer (upgraded), Vault or Gold Mine, plus Gun Turret and Cannon. Prioritize door upgrades.
How many waves are there?
Up to 67 on full runs. Easy difficulty ends earlier (around wave 20) for learning.
Do I need Robux?
No—the fifth unit slot is optional. Everything is achievable F2P with smart farming.
How do I unlock new maps?
Spend Gems from stage clears or complete previous maps on higher difficulties.
What if the door breaks?
Run ends instantly. Always upgrade and repair it first.
Are there codes?
None active right now, but future updates may add them—check the group announcements.
Personal Gameplay Observation
After grinding dozens of runs myself, the biggest “aha” moment came when I stopped rushing new turrets and instead maxed my Money Printer and one strong farm early. That single shift let me afford mythic upgrades by wave 30 instead of scraping by. The game rewards patience and planning more than raw reaction speed—once you internalize door-repair timing and S-tier placement, every run feels satisfying instead of stressful.
