Tips
  • Be prepared for fast-shooting enemies like Imps and Wraiths after certain events.
  • The area with Trites requires quick movement due to limited oxygen. Use fast-shooting weapons.
  • Chainsaw Zombies are dangerous; eliminate them quickly. The Chainsaw weapon is found after the PDA.
  • Aim for the head when fighting Cacodemon.
