Demonic Science is a very hard difficulty main quest given to the Hero by Dr. West in Dead Island.


The Hero must help two scientists in the Lab while Dr. West analyses the native blood sample.


  • Talk to Dr. West to start the quest.
  • He thanks you for getting the sample from the natives and asks you to help out the other scientists while he analyses it.
  • Only two scientists must be helped to achieve this. See their dedicated quest pages for walkthroughs and tips.
  • Once the two quests are completed, head back to Dr. West and talk to him to finish the quest.


  • Sometimes, after accepting the quest, the other two will not load. This can be fixed by restarting from the last checkpoint.
  • Completing any other lab related side quests will not advance the quest. It must be the two specified here.


  • "Demonic Science" is a song by the metal band Arch Enemy.
