"This is Private Sam Ackerman, 41st Engineering. I told them not to eat the infected. Then, they started changing. They became sensitive to bright lights. Just shining my flashlight would send them into a violent rage! I disabled the elevator to trap them down there. God rest their souls."
—Sam Ackerman

Private Samuel Ackerman was a soldier of the Sovereign Colonies Armed Forces and was present during the Necromorph outbreak on Tau Volantis in 2314.[1] He served as the Co-Op partner to Tim Caufman in the prologue of Dead Space 3.


The Events of 2314[]

Sam Ackerman was assigned to the 41st Engineering Unit located on the S.C.A.F. colony of Tau Volantis in 2311 in support of the archaeological and research operations there.[2] During the events of the Necromorph outbreak across the colony, Sam and the other survivors setted a defensive perimeter up in Facility RS-9 as they are convinced that they could wait the outbreak out within the safety of the bunker.

After Sam and his unit cleared the bunker of the Necromorphs, they piled the bodies and began to prepare defenses. It was not long until Sam noticed that the group's rations are spoiled, leaving them with no source of food.[2] It was suggested by one of the other survivors that they should eat the Necromorph flesh that was left over from the fighting in order to keep them alive. Sam knew that it was not a good idea and decided to stay away from the rest of the group while they ate the tainted meat.[2] While the soldiers began to transform into emaciated Necromorphs from consuming the infected flesh, Sam hid and avoided them for three days despite the infected sniffing him out at least once.

Sam managed to barricade himself into a communications room near the bunker's elevator while his former comrades begged him to let them in so they could eat him. Sam desperately sent a distress call out by looking for anyone that was still alive in the colony. His transmission was responded by Dr. Earl Serrano who asked him to link up with Private Tim Caufman on his mission to retrieve the Codex.[2] He disabled the elevator to trap them in the bunker.

Sam met up with Tim before they both pressed forward to collect the Codex for the doctor. When their search turned up nothing after 3 hours, Sam expressed his lack of faith in the mission and thought that nothing that they did would really stop the outbreak. Despite his constant complaining, Caufman pressed forward. Caufman and Sam followed Serrano's waypoint up a mountain to a crashed ship which was the Mule. Despite being attacked by the infected members of the ship, they managed to locate and secure the Codex. The Mule suddenly started to explode from the damage that it sustained during it's crash, forcing Tim and Sam to rappel down the cliff from the ship. The ship broke apart by causing the debris to rain down on the two soldiers before also severing their rappel lines, sending them tumbling down the mountainside and dodging the falling debris. Despite initially dodging most of the flaming wreckage including a piece of the ship's engines, Sam was eventually killed by the falling debris near the bottom of the cliff.

Tim was executed by General Mahad moments later who purged the Codex's information and killed himself, believing that they truly lost their colony to the Necromorphs and failing the companions' mission until 200 years later in 2514.


Sam was foremost a cynical soldier. He claimed that the mission for the Codex was hopeless, that both he and Tim Caufman are too inexperienced for the mission and when they found ammo, he snarked that at least they could shoot one another before they froze to death. He also appeared to be very resourceful and determined as he managed to survive at least 3 days trapped in a confined bunker, hiding from his infected comrades (Who probably also included several more experienced soldiers) while having little to no food before embarking on the mission to find the Codex.


  • Both Sam and Tim Caufman are equipped with Legionary Suits and S.C.A.F. Bullpup Rifles.
  • Like Tim, Sam wore an anachronistically-advanced RIG for the time period, had no Stasis or Kinesis module and borrowed his movement pattern from an existing character (Carver in this case). He also shared RIG upgrades with Carver.
  • Though Tim did not curse when stomping for an extended period, Sam did. His cursing voice was similar to that of John Carver's and quieter as if he was mumbling to himself.
  • Despite the introduction scene that was showing Ackerman (If playing Co-Op) with his helmet down in the middle of a snowstorm, his body temperature did not decrease and a meter did not appear behind his back.
  • Outside Co-Op Mode, Sam was never physically seen unlike Tim and Carver though his audio logs and history could still be found by the player.
  • A glitch can be caused if the Co-op Partner joins during one of the checkpoints of the prologue, depending on what suit was worn before joining, or if this is the player's first time playing, he could either be wearing an EVA Suit, a Special Forces Suit, or others.
  • A recent discovery shows that both Sam and Tim's model are dependant on their suit, if any other suit is equipped, while helmetless, it can show either Carver or Isaac's face depening on the suit worn, like for example the EVA Suit will show Isaac's face.
  • Unlike Isaac and Carver, Sam's Legionary Suit was visually identical to Tim's except for the red visor glow and the blue health line.
  • When Isaac entered the bunker where Sam and his group of survivors are staying, Isaac could find the audio logs that showed the different events that Sam experienced like how he saw the other survivors turning into Feeders.
  • As Sam was from the 41st Core Engineering unit, he most likely had fairly extensive engineering training, making him the 2nd playable engineer in the series.
  • Despite having been assigned to Hospitality Unit 213, far away from Archeological Facility Two, the Prologue had Ackerman starting on top of the mountain above Archeological Facility Two. No explanation was given on how he got there.
