Spider-Man 2 Greenwich district features only one Markoβs Memory collectible required for 100% completion and additional City Tokens. The Greenwich Markoβs Memory also provides even more information on Sandmanβs past, or how Flint Marko became the Sandman.
Assuming you have collected the four Financial District Memories and the two Markoβs Memories in Chinatown, you already know that Flint Marko turned into a hunter after discovering that someone was tracking him and his daughter Keemia Alvarado. His hunt led him to a Harlem school where armed people were waiting for him.
Now, letβs see what happened to him next by finding the Greenwich Markoβs Memory in Spider-Man 2 for PlayStation 5.
Where To Find the Greenwich Markoβs Memory in Spider-Man 2
As you can see on the map below, the Spider-Man 2 Greenwich Markoβs Memory collectible is found on the western side of the district, which I recommend visiting the moment you leave Chinatown.

Markoβs Memory #1 (Face To Face): On a Basketball Field
After reaching the location on my map, remain on the ground and look for a basketball field. Before approaching the collectible, get ready to be ambushed by Sandmanβs mobs. Luckily, as you can see in my screenshot, you have many basketballs you can throw at your opponents.
Get rid of them, then approach Sandmanβs Memory Crystal. Interact with it, then press L2+R2 to break it.

After you break the crystal, youβll hear Marko regretting leaving his home, searching for those he believes are tracking him. Keemia Alvarado, Sandmanβs daughter with Alma Alvarado, played an essential role in Markoβs life as a criminal. And you are about to find what happened next by opening the two Midtown Markoβs Memories Crystals.
After you find the one in Greenwich, youβll get a phone call from MJ, who informs you that Marko is feeling better and even started eating.
