doubts about the number of keys of Mortal Kombat XL from bundlestars

Mortal Kombat XL is a Steam package so likely you'll get a single key from BundleStars.

Edit: Or maybe not... :-)

mortal kombat xl from BS was 2keys for me -- mortal kombat x premium (base x game + kombat pack 1) & kombat pack 2 as the second key.
after double checking, i was wrong.. it came as 3keys for me as well.

HOWEVER

it states on the second line of the current promotion

Delivered as 3 individual Steam keys

so i'd say they split it down even more.

thanks :)
