You are in the deep space. Your name is Johnny. You wake up one day, and remember nothing. You find a paper on the floor that says:
"Sorry, Johnny. We had to leave. We rescued as many people as we could. Now it's your turn. Still, there are not infected people on the ship. Find them, at least three, and go to the evacuation room.
Tip1: infecteds won't attack you if you don't move
Tip2: survivors will follow you, but don't run fast, they are slow.
Important: if a survivor is closer to an infected than you, she will be the target and she will be INFECTED! Don't let it happen!
