The second iteration of 2v8 is now LIVE - find out more information here: https://forums.bhvr.com/dead-by-daylight/kb/articles/480-2v8-developer-update

The Shape Shifter

Has the ability to shape shift into a survivor - with same look as the ones that joined the game, selected randomly when using the ability - for a short period of time, causing no terror radius.
Can only attack if shape shifting back into the killer.

Would be fun if survivors could not trust one another.
