StarCraftII ?

Hello everybody.
I am realy curious if there is a possibility to play for free StarCraftII with my friends( including some fun maps) ? If there is, could somebody give me a short guide in english with links where to download the necessary files?

Sorry if i re-opened a post, but i didn't find any about this idea, and most of them were in german.

I dont know a method to play Sc2 dir free just the starter Edition but thats not really Sc2 dir free
Buy wings of libertiy its cheap and you can play :)

There is no possibility to get a free WoL or a HoTS license,just with the Beginner-Edition, but there you can only play Terran.

So, buy the game ;)
