Tips
  • The Super Shotgun is excellent for close-quarters combat and dealing with the initial threats.
  • Utilize the environment for cover, especially when facing hit-scanners and the Revenant.
  • The bloodfalls can be used to your advantage to damage enemies or detonate explosive barrels.
  • Save powerful weapons like the Rocket Launcher and Plasma Gun for tougher enemies like the Revenant, Chaingunners, and Pain Elementals.
  • Be cautious in dark areas and open spaces where enemies can ambush you.
  • The BFG9000 is a powerful reward on lower difficulties, use it wisely.
