You run,jump,climb etc until you reach a door at the end.You open it and walk up some stairs.The room seems to be like a control room.Someone waits there

"Greetings my friend" said the man
"Who are you and what am l?" you say
"You can call me Proffesor X"
"Who am l?"
"You are a killer,a hitman if you like and your needed for a kill"
