FBI special agent
An agent of the American Federal Investigation Bureau, that is FBI, suddenly went missing from his residence a few days ago while on a secret mission in Russia... (it is likely that he has been killed).
You are his colleagues, you all are FBI special agents, you have been ordered to enter in Russia secretly to investigate his disappearance.
After entering his room you realize that the door has been mysteriously locked. You have a limited time to investigate and then flee.
Good luck to you all!
