Can You Beat Dishonored Using ONLY Rats?

Can you beat Dishonored using ONLY Devouring Swarm? I decided to find out how far I could get through Dishonored while restricting myself to a single ability: Devouring Swarm No other powers or weapons at all. This was weird... If you enjoy stealth games, challenge runs, or Dishonored, stick around. #dishonored #stealth #challengerun #dishonored2
