Lead your soldiers in real-time combat against iconic Xenomorphs, rogue operatives from the insatiable Weyland-Yutani Corporation, and a host of horrifying creatures new to the Alien franchise.
You are the commander. They are your weapon.

Customize your squad with a selection of different classes. Level up and specialize your soldiers with unique abilities and an arsenal of weapons, armor, and perks, for high stakes missions in treacherous territory. Develop your base to research new tech and improve your squad even further.
Manage your resources wisely and take calculated risks to outsmart the deadliest creature mankind has ever faced. Can you and your squad stop the outbreak before it’s too late?
• Face off in a gripping original Alien story against iconic Xenomorph creatures ranging from Facehuggers to Praetorians, Alien Queens and many more, including rogue human commandos and a brand-new threat unique to this Alien storyline
• Lead strategically and change squad tactics from mission to mission, carefully managing your soldiers’ health, resources, and sanity, to avoid permanent team losses and mental breakdowns
• Forge unique paths for survival in a persistent world, uncovering shortcuts, creating safe zones and setting up motion trackers to stay one step ahead of these creatures
• Assemble and level up squads composed of 5 starting Marines classes, with dozens of specializations, unique abilities and weapons.

Hi everyone,
Thanks to your feedback, we worked on a hotfix to resolve the issue regarding your missing marines when launching a New Game + campaign. We are sorry for the inconvenience and hope you'll have a great time facing the new difficulty parameters we brought for you in the last update.
You should now properly get your marines when creating a NG+ campaign using a save created before the release of the New Game + Update but please note that in some cases the experience won during the Mission 11 Olduvai Dig Site will not be saved. If you want to be sure to have your marines with the experience gained during that mission please follow those steps:
Disclaimer: This hotfix is aiming players creating New Game + campaigns based on campaign saves that were created before the release of the New Game + update. For the players that already created a NG+ campaign and have some marines missing, you will need to create a new NG+ campaign if you want to get back all your marines. We are once again sorry for the inconvenience.
Thank you for your patience. Have a great time playing Aliens: Dark Descent!
Hi everyone,
We released a hotfix yesterday that was aiming to fix a bug where marines were missing when creating a New Game + campaign. Unfortunately when we released the patch some players reported that it was now impossible to create a New Game + campaign using a save from a campaign dating from prior the New Game + update.
We immediatly looked into it and we fixed the issue. With this hotifx you will now be able to create a New Game + campaign and get all your marines just like it was intented. You should now be able to correctly create a NG+ campaign using a save from a campaign created before the release of the New Game + update.
Like we said in the patch note yesterday, in some cases the experience won during the Mission 11 Olduvai Dig Site will not be saved. If you want to be sure to have your marines with the experience gained during that mission please follow those steps:
We are truly sorry for this unexpected bug and hope you'll have a great time playing Aliens: Dark Descent.
Thank you for your patience and your passion.

- DISTRESS SIGNAL -
Attention, this is a Priority One distress message from the survivors at Jackson's Landing on the planet Lethe. We are broadcasting on all available channels.
The situation here has escalated to a critical state. All lines of communication with governance and security forces have been severed.
The creatures we are facing grow increasingly dangerous, showing new capabilities for rapid nesting and expansion. The situation is desperate.
Some of our scouts have reported seeing a contingent of Colonial Marines engaging the creatures. They appear seasoned, experienced in combat, and potentially knowledgeable about the threat we are facing. While it is unclear how they are faring, any information they possess could be invaluable to our survival.
If this message reaches anyone capable of providing assistance, we implore you to relay our distress signal to the Colonial Marines stationed on this planet—or better yet, come to our aid yourself.
You are our last hope. Please, help us.
End of Transmission.
