  • Fight the zombies as long as you have high HP. Beware of zombies that can do critical damage.
  • Don't be reckless, otherwise dying will result in restarting all over.
  • After an amount of HP recovery, you need to wait for a period of 1 hour and 30 minutes before your HP can be recovered again.
  • Deimos is likely to do critical strikes most of the time. Make sure to spare your HP more than 500 as the critical strike may kill you in an instant.
