(Bug/Feature) - look through walls

Greetings!
At the source, where I found a video of a bug “Long Hands” there was a revolution. All players have begun to share their bugs and tricks with the author of the channel.
It turns out there is a team for a long time “injure” which introduces you to the defeated state, but life is not consuming.
This feature is easy to view the walls of houses.
I fix for this team.
