"Thought I was a goner"
Chris Duplis to Winter

Chris Duplis was a member of the United States Colonial Marine Corps. He was part of a search and rescue mission sent to LV-426 aboard the USS Sephora in 2179 to investigate the disappearance of the USS Sulaco and its crew 17 weeks earlier. He went M.I.A. soon after being rescued.


"Let's rock this!"
Chris Duplis

Chris Duplis was one of the Marines who survived the destruction of the Sephora and Sulaco, making it safely to LV-426. Duplis was inside Hadley's Hope's Operations center fighting Xenomorphs when he found himself trapped inside one of the small rooms of the facility.

When Corporal Winter arrived, he quickly cut the locked door opens with his ME3 Hand Welder and as soon as Winter opened the door, Duplis was pounced on by a Lurker which Winter quickly killed, saving Duplis.

Afterwards, Chris, Winter, Angie and Maio then regrouped downstairs with Private O'Neal and Captain Cruz. While Angie followed the others into the Vehicle Bay, Maio and Chris held the position, using M314 Motion Trackers to keep an eye out for any more Xenomorphs. Both him and Maio were then rendered M.I.A.

Maio was outfitted with standard-issue M3 Pattern Personal Armor for protection; his armor was fitted with a TNR Shoulder Lamp attachment for illumination. The front of his armor had most of the paint scratched off from the Lurker that attacked him. Chris kept a knife on his left boot. Chris also had two shotgun shells and three spare rounds strapped on either side of his combat vest. Chris was armed with an M4A3 Service Pistol and an M41A Pulse Rifle MK2. He also carried an M314 Motion Tracker.


  • This character is the in-game representation of costumer and Aliens fan Chris Duplis. Duplis was given his cameo appearance as a thank you from Gearbox Software and SEGA of America for his work promoting Aliens: Colonial Marines. His in-game appearance was modeled using his actual likeness as a reference and is also one of the male Marine head options in Multiplayer Customization.
    • Chris Duplis, Angie Duplis, and Sean Maio were the three American members of the "Aliens Legacy" fan group who were hired by SEGA of America to be characters at the official Aliens: Colonial Marines booth at the E3, Penny Arcade Expo, and various other game industry events across the U.S. from early 2010 to the game's launch in 2013
  • If the player does not shoot the Alien pouncing on Chris in time, Chris will push it off himself.
  • Although he is normally immune to any attacks (including Xenomorph ones who besides the Lurker that pounces on him will not actually attack him) killing yourself with a U4 Firebomb (including the ones fired by the U4 Firebomb Launcher) whilst close to Chris will cause him to perform a fire death animation along with the player.
  • A male player named "Duplis" is seen In one of the Bug Hunt DLC screenshots on the DLC's page in the Steam store.[1][2]
  • One of Chris' lines, "Let's rock this!", is an obvious reference to the famous line said by Jenette Vasquez in Aliens.
  • Interestingly Chris' in-game hair is more brownish while the real-life Chris has blond hair, Maio's hair is also similarly darker than it should be.
  • While never explicitly stated in-game, it can be assumed that Chris and Angie are married as they are in real life.
