Marvel Avengers Alliance Spec Ops 13 Guide

Coming clean, I'm an addict for Playdom's Marvel Avengers Alliance and I swear I can effing play this Facebook game for a whole day. That being said, the game just launched it's big "Infinity" tie-in with Special Operations (Spec Ops) # 13 which features Thanos and his Black Order together with Inhuman king Black Bolt and a new hero Thane.

So if you want to get either one of the two, I suggest you start playing the game (which is very INFINITY-spoiler heavy mind you) and hope for the best. I would like to cite The Marvel Avengers Alliance [Philippines] group  particularly James Noele Vasquez who created the document.

Then there's also Thane. To get the supposed and rumored 'Son of Thanos' you have to gain themed lockboxes. Here's Thane's bio (special thanks to Bleedingcool):

Additional story for Thane:

"I used to be just a man. Just another healer, nobody of consequence, plying my trade among my people. And then Thanos arrived. How did I get these horrible powers? Why? Did they come from him? All I know is that just as he came to Earth, I… changed. Suddenly I had the power of life and death in my hands. But I could not control it, and the people around me paid the price. Everyone that I had once healed, everyone I knew… dead. I ran before I could kill again, only to find an even greater murderer in my path. Thanos and his lieutenants were coming… for me. This Thanos creature… what does he want from me? If I give myself up to him, will he stop killing people? Or will he just use my powers to kill even more? I need someone to help me understand what I am… what I’ve become. Is that you, Agent? Do you think you can control death itself? I doubt it. But the truth is, I have no other choice. I cannot go back to the way I was, and I cannot go to Thanos. That leaves me with you. But I warn you. Try to use my powers for evil, and I’ll show you what they can do… in abundance."
