Jason Voorhees ia a movievillan in boss pack 1, He is just like other hit and run bosses, spawns behind the players, giving no mercy to the sprint or the players hit, Jason has a method to catch a person, first he will target a person to chase, after the chase for a few seconds, if the area has a very large rooms to fit in and can be spawnable for Jason, Jason will spawn and will chase the player, and will keep doing that until the player is dead or the player found a very crowded place for a hit and run boss not making spawns, Jason, Scarecrow and Walrider appear to be the only hit and run bosses that much more persistent than the others, chasing some people for over 10 seconds.
