Aliens Dark Descent: Guide content

Our guide to Aliens Dark Descent opens with tips and tricks, in which you will learn important things about reacting to dangers, giving orders, or properly using supplies and accomplishing mission objectives. The chapter about the game's basics describes all difficulty levels, all weapons and abilities, the most important elements of the user interface, and the main types of enemies.

In the FAQ section, we answer the most frequently asked questions. You can find out, among other things, whether you can completely pause the game, how to save your progress, how to heal and revive marines, whether you need to race against time, how to correctly read information from the motion tracker, how to acquire a smart gun weapon, how to open locked passages, or how to react to high stress levels among your soldiers.

In the walkthrough section, you will find solutions for all story missions where we discussed the main and optional objectives, as well as recommended tactics and optimal paths to story-related locations. We have also included a chapter on secrets and collectibles - you will learn where to find the secret items and how to explore the locations in 100%.

The main chapters of the guide are supplemented primarily by a trophy guide with instructions on how to get 100% of the game's achievements and unlock the platinum trophy. On separate pages, we have described, e.g. the controls, system requirements, game length, availability of multiplayer and co-op, and whether the game makes references to the to Alien movies.

Aliens Dark Descent: Tips and Tricks

  1. React to the motion tracker's readings. This is crucial when preparing to fight xenomorphs and other enemies.
  2. Use active skills regularly. You can, e.g. set up suppressive fire or use shotgun blast. These skills use command points, but they regenerate automatically.
  3. Use surprise attacks as often as possible. Fighting xenomorphs exposes marines to the risk of losing their lives and may increase the level of aggression in subsequent monster attacks.
  4. Search the containers and the corpses. You can find useful supplies, and, in some cases, you can also get unique secrets and collectibles.
  5. Have your squad consist of marines from various classes. Each of the 5 classes of soldiers specializes in a certain field (e.g. medic) and their abilities can be very helpful in increasing the team's survivability.
