Im probably the biggest fan of Xcom Enemy Within and Unknown and now with it on Android I finally broke down and got it and the main reason is unlike the PS3 and 360 versions this one has Random generated missions, with that said although it takes 3.5 gb im still glad i got it.

XCOM: Enemy Unknown is out now on Google Play, commander. The new Android port is priced $10/£7.14, and according to a message from XCOM HQ, an advance on the Amazon Appstore is expected "soon."

Despite claiming the lives of many of our best friends - or at least a bunch of soldiers named after them - we rankedEnemy Unknown as our second-best game of 2012. The good news: Firaxis transitioned the console and PC release into a " slick, portable package" on iOS, and hopefully that'll pan out the same way on Android.
Awesome game. I haven't had time to really play it a lot though.
I play this on my ipad. I know u hate apple products, but we can agree Xcom is great on the go! 
Well Snee I wouldnt say I hate it I mean apple is good for everyone but me lol!! And yes they really did an awesome job on the transition to mobile and I heard Xcom Enemy within is headed to apple as well but a game you should check out is Ground Pounders this is a cool game just check out my pick of the month on it.
