THE SYMPTOMS

Felix Kjellberg accepts the challenge to scavenge the Paris Catacombs in complete darkness under the notion that the obstacles that await will do no more than give him a small fright, but otherwise leave him completely unharmed. The challenge takes a terrifying twist when he is instructed by an anonymous voice to fight against blood-thirsty creatures that lurk within the tunnels in order to save his girlfriend Marzia. However, the only person he really needs to be saving is himself.
