Q: Why are you camping ?
A: It's a valid strategy as the developer of this game said, but I usually use it whenever you will gen rush me faster than a marathon. Please watch this video if you don't believe me:https://www.youtube.com/watch?t=30&v=SS3DvvOQI04&feature=youtu.be .

Q: Why are you using No One Escapes Death ?
A: Why not? Seriously now, it's a good perk for killer to get back some pressure and in general to get a comeback. Also you probably are using good, even meta perks too, e. g. Borrowed Time, Unbreakable, Dead Hard, Decisive Strike or Adrenaline.

Q: Why are you tunneling ?
A: It's simple. I want a kill since I am a killer ¯\_(ツ)_/¯
I base my decision about tunneling on how fast or how many gens are done.
