Tips
  • Save frequently at Terminals (fast travel points).
  • Pay attention to boss weaknesses and resistances to optimize combat.
  • The minimap (on your HUD (heads-up display — the on-screen icons showing health, ammo and the minimap)) is crucial for navigation.
  • Use the radar (your minimap with nearby blips and threats marked) to locate quest objectives and enemies.
