Dummy Defense MK1 titan dummy: How to Unlock

You unlock the Dummy Defense MK1 titan dummy by collecting four lobby items for The Crystals Tape badge, and you deploy this prototype defender to fight invading forces. After completing the collection route, you purchase the unit with Bricks in the shop.

What Is the MKI Titan Dummy in Dummy Defense?

The MKI Titan Dummy is a heavy mechanical tower designed to combat alien invaders like Noobs and Guests. Lore records from the YouTube video The LORE of Dummy Defense describe Frimmour as the original MK1 Titan prototype, created using crystal power to fight the boss Goob during the early war.

The official Roblox game page lists the MKI Titan Dummy as a badge-gated shop unit created by Mr Lazy Guy Studio. Earning the badge removes the lock on the shop slot. You must spend regular Bricks to buy the tower, and deployment requires in-match Cash.

Where Are the Four Crystals Tape Lobby Items?

Lobby collectibles are hidden stationary objects scattered across the main waiting area rather than combat drops in match modes. You must collect three paper documents first before picking up the VHS tape.

1. Locate the first document at the metal shelving near the central shop area, tucked underneath the shelf structure.
2. Walk into the AFK zone and check behind the water dispenser beside the seating tables to grab the second document.
3. Move toward the Skins counter area and inspect the corner behind the barrel beside the bush to collect the third document.
4. Return to the shop display area to retrieve the VHS tape located behind the image frame on the table.

After collecting all four items, the system grants the crystals tape badge. You can insert the VHS tape into the lobby television set to review its lore recording.

How Do You Choose Between Badge-Locked Towers?

Badge-locked towers are defense units that require specific operational milestones or secret lobby collections before you can spend Bricks on them. The Dummy Defense lore and tapes guide notes that lobby pickups require no combat clears, making them accessible before tackling late game modes.

While the MKI Titan Dummy unlocks through exploration, the titan scale dummy demands a victory against the boss encounter in Controller Mode. Both units provide heavy defensive support once added to your loadout.

How Do You Obtain the Void MKI Titan Dummy Skin?

The Void MKI Titan Dummy is an alternate cosmetic appearance obtained by completing the four-step elyndra quest. This quest line operates separately from the standard lobby item hunt. Completing each task in sequential order awards the Elyndra badge, a special title tag, an additional lore tape, and the Void skin variant inside the shop menu. Progression toward standard badges does not count toward the Elyndra objective, requiring you to finish its designated tasks individually.
