- "Collin, Get your guys over here! He's this way!"
- —Circle member
Based on the first (and only) radio transmission where his name was heard Collin was probably a high ranking officer in the Circle, as he leads his own squad with an Unitologist Dropship.
Collin is not seen or heard of anymore after the radio transmission, so he may have died sometime after it was sent. He was most likely killed during the firefight after Isaac descended from the cargo lift, either by him or by the numerous Necromorphs swarming at the far side of the zone.
