There’s definitely substantial potential for PvPvE if you make the E portion challenging enough. I hosted a few battle royale events on a DayZ server with dangerous mutants, which were particularly concentrated around the final zone, and it was a lot of fun. I remember at one point seeing a calculated last minute betrayal leading to a firefight with another survivor who heard the shots nearby, which then led to both of them being attacked by a monster. The chaos of it all was a lot of fun.
