Defend your base from 67 is a tower-defense base-builder created by Simulator D2D. Each match places you (and up to 24 other players) on a shared map where every person gets their own private base plot complete with a door and a handful of build spots.
The villain is the 67 worm — a giant, meme-worthy boss that marches toward your door in escalating waves. Your job is simple on paper but demanding in practice: keep the door alive long enough for your turrets to chip away at the boss’s health until it either dies or you survive every wave on your chosen difficulty.
The game launched on February 12-13, 2026 and already sits at over 17 million visits with tens of thousands concurrent players. It’s tagged as Strategy / Tower Defense and runs in servers of up to 25 people, so matches feel lively but never overcrowded.
How to Play
- Lobby Phase Spawn in the lobby and spend coins (earned by damaging 67 in previous runs) to summon crates. Each crate unlocks random tower units. You can equip up to four towers for free; a fifth slot is available via Robux.
- Choose Your Base Once the round starts, run to an unclaimed base plot. Every base has a central area where your Money Printer automatically appears, a front door, and limited build spots for turrets and farms.
- The Core Loop
- Upgrade your Door as soon as the upward arrow appears — it raises HP and unlocks higher-tier upgrades for everything else.
- Place offensive turrets near the door early.
- Build and upgrade Money Farms for steady income.
- When 67 reaches your door it starts dealing damage. A repair button pops up at the bottom of the screen — tap it quickly but watch the cooldown.
- Keep upgrading and repositioning towers as waves get harder.
- Win Condition Reduce the 67 worm’s health to zero or survive all waves on your difficulty (Easy mode typically ends around wave 20). Each player wins or loses based on their own base, so teamwork is optional but helpful for morale.
Core Gameplay Features
- Individual Bases in Shared Servers — Everyone defends their own plot, creating satisfying “my base vs. the worm” moments while still seeing friends’ towers lighting up the map.
- Economy Management — The Money Printer gives early passive income; Money Farms scale into the real cash engine once fully upgraded.
- Tower Variety — Basic crossbows for early waves, flamethrowers for crowd control, and rare drops like Dragon Launcher, Lava Launcher, Black Hole Generator, and Laser Cannon from Galaxy Crates.
- Door Repair Mechanic — Forces active attention during boss pushes instead of pure AFK tower placement.
- Multiple Maps — Forest (starter), Desert, Frozen, Lava, and a limited-time Galaxy map. Lava map is especially popular right now because the visual chaos matches the brainrot energy.
- Difficulty Levels — Easy for learning, harder modes for longer waves and beefier boss health.
- Crate System — Regular crates and the shiny new Galaxy Crate during the current update give the gacha thrill without pay-to-win pressure.

PC

Tips and Beginner Strategies
Start every run by rushing Door level 2 or 3. It gives you breathing room and unlocks better Printer upgrades.
Place one or two cheap offensive turrets (crossbow is perfect) right in front of the door for wave 1-3, then immediately pivot to Money Farms. Economy snowballs harder than raw damage in the mid-game.
Save your repair button for big hits — spamming it early wastes cooldowns when you need it most.
On Lava map specifically, spread your towers wider because the terrain funnels the boss in unpredictable ways.
Don’t sleep on the lobby crate summons. Even a few regular crates can give you a strong early-game tower that carries you through your first ten wins.
Personal gameplay observation: In one of my early Forest runs I went all-in on flashy turrets and ignored the Money Printer upgrades. By wave 8 the 67 worm was healing faster than I could damage it, and my door crumbled in seconds. After that I switched to “Door → Printer → Farms → DPS” order and suddenly started clearing Easy mode consistently.
Progression System / Upgrades / Rebirth
Progression is entirely in-run upgrades plus long-term tower collection.
- Door upgrades act as the gatekeeper — each level increases HP and lets you buy higher Printer and Farm tiers.
- Money Printer upgrades are the single biggest power spike early on.
- Money Farms require heavy investment but pay for themselves many times over by wave 10+.
- Tower upgrades (once placed) increase damage, range, or add special effects.
Crates are your meta-progression: every run you damage 67 you earn coins to roll for better units. The Galaxy Update introduced the Galaxy Crate with mythic-tier towers that make late-game runs much smoother.
There is no traditional rebirth or prestige system at the time of writing. Instead the game rewards consistent play through better tower unlocks and badge progression (first game, Easy win, opening five crates, etc.).
Why Players Enjoy This Game
The loop feels fair. You never feel completely helpless because a single smart upgrade or timely repair can turn a losing wave around. The brainrot 67 meme gives it personality without getting in the way of actual gameplay. Short matches (10-20 minutes on Easy) make it perfect for quick sessions, yet the deeper economy and crate chasing keep dedicated players coming back. Plus watching your friends’ bases explode while yours barely holds on creates hilarious shared moments in the 25-player servers.
Frequently Asked Questions
How do I unlock new towers? Summon crates in the lobby using coins earned by damaging the 67 worm in actual games. Better crates (including Galaxy Crate) appear during updates.
What is the best early-game strategy? Door to level 3 → upgrade Money Printer → place 1-2 crossbows → build Money Farms. Everything else comes after.
Is the game pay-to-win? No. The fifth tower slot is the only Robux purchase and it’s optional. All powerful towers are obtainable through normal crate summons.
How do I repair the door? A big button appears at the bottom of the screen whenever the boss is attacking. Click/tap it, but respect the cooldown or you’ll be locked out during the next big hit.
Which map is hardest? Lava is currently considered the toughest because of tighter space and faster boss pathing. Galaxy map is limited-time and equally brutal.
Do I need friends to win? Completely solo-friendly. Other players don’t affect your base directly, though seeing their strategies can be inspiring.
Are there codes or free rewards? No active codes at launch. Check the official Roblox game page or the developer’s Discord for future giveaways.
Defend your base from 67 is the kind of Roblox game that sneaks up on you. Ten minutes turns into an hour, one Easy win turns into chasing mythic towers on Lava, and suddenly you’re explaining to your friends why the Money Printer upgrade order matters more than raw DPS. If you like tower defense with a side of meme chaos, this one is worth claiming a base today.
