Buy mac edition, apply the code to your current account. Can play on PC still.
A standalone version of valkyrie pack will be out pretty soon as well. But the mac edition is a better deal.
brill, thank you 
i shall download it now
/RE-EDITTT.
Well, i think the store is down, i cant purchase the mac edition in-game pack, cant buy it with Credit card, OR paypal, gives me the following error.
We're sorry, but we are unable to accept your order at this time, please try again later or tomorrow. ._.
possibly a silly question but how do i get it?
is it part of the mac special edition pack and not seperate like the cyborg and wedding packs?
and if so, can i use it without having a mac?
thanks
