- "ONE TIME I HEARD IT SEEPED OUT OF THE ENCLOSURE AND MELTED A GUY AND THEY HAD TO QUARANTINE THE AREA"
- —Cursor, on 619.
Unit 619 was first mentioned in a Q&A with Cursor. It's described as a highly acidic blob capable of dissolving large amounts of biological matter.
Prior to 2016 Edit
At an unknown date and time, 619 was captured and contained by the Wyndstrom Institution. As of current, it resides in containment, and will remain there for the foreseeable future.
619 is made of an entirely acidic, jelly-like substance that is apparently capable of dissolving humans. It is unknown if this is the only thing it can dissolve.
