Heart of the Swarm after 12 missions

The game is finally live and I'm like 6-8 hours in and 12 missions or so completed and I must say its the best story I've experienced in a few years. Like if I could get the Predator, Aliens and all the other sci-fi movies I loved over my lifetime wrapped into one unique story with all of the elements I crave.
Oh and I get to play it too. :) very impressed so far. Can't wait to see more ....
