Marachuk was attacked by a Facehugger in the sub-level access tunnel to the Atmosphere Processor some time after Hadley's Hope was exposed to the Xenomorphs, where he was discovered. The attempt to surgically remove the creature before it could implant a Chestburster inside him ended disastrously: the colony's surgeon, Dr. Biggs, made an incision across the Facehugger's back and consequently was sprayed across the face and throat with acidic blood, killing him. The Facehugger was then pulled off by two medtechs and secured in a specimen jar; Marachuk himself was killed in the process.
