There's a new Kill Pack available for Friday The 13th: The Game. It is only $2.99, and here's the description:
Experience three all new grab kills for Part 2 Jason Voorhees with his Pick Axe.With weapon swapping now available at Level 113 and higher, it's important to clarify that this Kill Pack works with the Pick Axe and isn't just tied to Part 2 Jason any longer.
Kills included are the 'Curb Stomp,' 'Top Popper,' and 'Sweep the Leg!'
These kills are exclusive to Jason Part 2.
I've already purchased it via this link, and will try it out ASAP.
