The Lost Signal: SCP

Agent, you were taken to the underground complex for a special mission called The lost signal SCP. Assignments you get by going to a special black screen. They seem ridiculous to you, but orders are not discussed and as a result you will understand that all tasks are related to each other and from successful fulfillment of one, the transition to the next depends. Begin moving along long, branched corridors. Collect the items necessary for the success of the mission. The labyrinth seems endless and you have lost the signal on the phone. Contact the command to get tips or tips you can not. Hope only for your smartness and logical thinking.
