Defend your base from

Defend Your Base From 67 is a co-op base defense game on Roblox developed by Simulator D2D, launched in February 2026. In under three months it surpassed 120.5 million visits - one of the fastest growth curves in its category. The game draws 1,000 to 5,000 concurrent players across 25-player servers and holds an 89.8% approval rating from over 100,000 voters.

The central threat is "67" - a giant worm-like creature that has escaped and is trying to break through your base doors. Players must fortify their defenses and coordinate with teammates to stop it:

• ⚔️ Stop 67 - prevent the giant worm from breaching your base doors before it breaks through
• 🏠 Upgrade Doors - strengthen the primary barrier that stands between 67 and your base interior
• ⚔️ Place Turrets - set up automated ranged defenses that engage 67 and other threats
• 🏆 Difficulty Modes - challenge yourself on Easy Mode or push through harder difficulty tiers
• 🎭 Co-op Defense - coordinate with up to 24 other players to cover all base entry points simultaneously
• 🏆 Badge Progression - 23 badges track achievements across difficulty tiers, wave milestones, and upgrade goals

The 25-player server cap is unusually large for the genre and is central to the experience - enough teammates to split roles across door upgrades, turret placement, and active combat while 67 escalates its assault.

Defend Your Base From 67 sits alongside classic co-op tower defense titles but narrows the focus to a single, characterful threat. Its explosive early growth and 4-place structure suggest continued content expansion from the verified Simulator D2D studio.
