Dummy Defense Crystals Tape Locations and MKI Unlock

The Dummy Defense crystals tape is a lobby collection quest where players gather three hidden documents and a VHS tape. Finishing this secret run awards the lobby badge and opens the MK1 titan dummy for purchase in the store.

Where Are the Crystals Tape Items Located?

The Crystals route is a four-step pickup path situated entirely within the main lobby area. You do not need to enter combat matches, defeat wave bosses, or clear special difficulty modes to collect these items. According to the lore and tapes guide on dummydefense.wiki, players should orient themselves using the permanent lobby landmarks, including the shop counter, seating areas, and display signs.

Collect the four items in the following sequence:

1. Document 1: Walk to the metal shelving units placed near the SHOP sign. Inspect the shelves and pick up the loose sheet of paper lying on the rack.
2. Document 2: Head over to the AFK zone seating area. Walk behind the water dispenser positioned beside the tables to find the paper tucked into the narrow corner.
3. Document 3: Move across to the decorative foliage beside the right-hand Skins sign. Pick up the third document resting in the corner beside the bush.
4. VHS Tape: Return toward the shop area and locate the standalone table. Collect the VHS tape resting on top of the surface to complete the four-item objective.

Dummy Defense badges are not trophies — they are the game's unlock system.

What Rewards Does the Crystals Tape Unlock?

The Crystals Tape badge is an account unlock that makes MKI Titan Dummy available in the unit shop. The official badge description notes that players must find all four items to unlock the badge, which also permits using the tape with a television set in the lobby. Interacting with the television opens the VCR and Tapes interface to review the unlocked recording.

Earning the badge removes the lock condition on the shop entry. It does not deposit a free unit into your inventory, nor does it bypass match deployment costs or account level prerequisites. Once the badge registers on your account profile, you can spend your accumulated Bricks to buy the unit directly from the standard merchant roster.

How Do Crystals Compare to Other Secret Tapes?

Lobby secret badges are non-combat objectives that grant specific store entries or cosmetic lore tapes. Unlike regular combat badges that require clearing difficult bosses, secret tapes depend entirely on exploration and interface interactions. As documented on the badge list on dummydefense.wiki, each hidden badge targets a distinct collectible or profile reward.

The sphere faction news tape activates randomly while interacting with matchmaking menus, while the elyndra quest involves four structured tasks that yield an alternate skin. Finding the hidden NPC for meet angelo provides background lore without granting a store entry. Gathering the Crystals documents remains the only lobby exploration route that opens a mechanical titan unit in the shop.
