In order to achieve the objective you will have to use the light equipped on all the Operative's weapons, to which the Archaeans react if they are close enough to the wall, but to make them bioluminescent, you will have to get as close as possible, so that the head and the heart of the enemy begin to shine and move.
This will allow you to tag them for your peers or as a point of reference. In addition to allowing you to locate them without being detected.
That's all you need to know about how to make an enemy bioluminescent in Rainbow Six Extraction, so we hope you get a lot out of this strategy.
