Markoβs Memory in Williamsburg District of Spider-Man 2 counts as a collectible and allows you to continue investigating what happened to the Sandman before the events in the video game developed by Insomniac Games. The Williamsburg Markoβs Memory crystal is required to obtain 100% completion and to start the Remember side mission, which serves as an epilogue for Sandmanβs story.
If you followed the order on our Spider-Man 2 Strategy Guide, Markoβs Memory in the Williamsburg District is the twelfth collectible you should get, following the one in Downtown Brooklyn. The crystal unlocks the memory or audio log named Imprisoned.
Where To Find the Williamsburg Markoβs Memory in Spider-Man 2
On the map below, you can notice that Markoβs Memory collectible in Spider-Man 2 Williamsburg District is found in the northwestern corner of your map. You donβt have to uncover the whole district to get it or to progress the story. Just make sure you reach the location I have marked for you.

Markoβs Memory #1 (Imprisoned): On Top of a Factory Building
Markoβs Orange Memory Crystal at the location I have marked above is on top of a red factory building. When you get close, look for the factoryβs stack on the roof, then climb the building. Youβll find the crystal on the buildingβs roof in my screenshot below.

Before getting close, make sure you are ready to face Sandmanβs thugs that will spawn and heal if needed. There is only one wave of enemies youβll have to deal with before being able to approach the orange crystal and interact with it. After you break the crystal, youβll unlock the Imprisoned Memory.
According to the audio log, after returning home, Flint Marko was captured by his hunters and brought to a dungeon. The identity of his captors remains unknown, but it is clear that Flint Marko struggled and suffered because he didnβt know if his daughter Keemia Alvarado was still alive. To continue your investigation, youβll need to retrieve the Little Odessa Memory Crystal.
