So there is no point of the game other than to go around and kill other people weaker than yourself.
It's doesn't sound like a "survival" game at all then, unless by "survival" you mean to avoid other people at all costs who are out to steal your flashlight, until you somehow can access enough hardware to kill other people with flashlights.
They should just call the game "FlashlightZ".
When does it get fun? When you can succesfully kill other newbs easily (provided your character can live that long)?
I'm trying not to sound cynical, but seriously.. it's hard when descriptions of this game's obective is to kill weaker players as fast as possible so that they don't advance.
Have you ever played DayZ? If not, then its hard to explain it to someone who doesn't understand what is trying to be explained.
Your simple "description" of the game can be applied to near every shooter game. "Whats the point? Just to kill people?", and you can probably make a single statement like that for every single videogame genre.
