Phobos' DNA Sample was a special item available in Counter-Strike Online.

This item is no longer obtainable after the Zombie Scenario Re:boot patch.


Phobos' DNA sample can be obtained by defeating Phobos in Last Clue. It can be combined with Operational Map, Damaged Equipment and Andrey's Diary to receive Dr. A's Trunk.


Phobos' DNA sample itself is a parasite that is obtained after defeating Phobos. The parasite jumped out from Phobos' left hand and get caught by the rescue team. Heading for the Rex basement, the rescue team transported the DNA sample for an experiment.
