I'd advise anyone looking to get it for the PS4 to hold off for a day or two. The servers seem to be up but the latest patch has disabled voice chat which is pretty vital if you actually want to survive.
On the plus side i had my first Jason game and it was hilariously easy because no one could talk
It's getting quite irksome though, the game has it's flaws but it's legitimately entertaining to play and it's addictive as hell but the server issues and the mic issue are getting on my tits.
