Tips
  • Use Xtraction Points to save your progress and fast travel between discovered points.
  • Look for collectibles like Black Box Recorders, Comic Books, Sketchbooks, and Data Discs.
  • Destroying optional objectives like the Radar Array, Insect Drones, Egg Clusters, and Cerci Queens grants extra XP and rewards.
  • Pay attention to the minimap (the small radar display in the corner of your HUD (heads-up display — the on-screen icons showing health, ammo and the minimap)) for objective markers and enemy locations.
  • Utilize cover (press the cover button to crouch behind walls or objects) when engaging enemies to minimize damage.
