The Arcade / Custom Maps for Starcraft II are now free to play for all!
UMS were my favourite part of the first Starcraft game (and Brood War) but the Arcade on release and even after the second Zerg expansion/game/marketingploy/whatever it seemed pretty lacklustre. Don't get me wrong, many fun times were had. It just felt weird and different.
Now they're putting more power than ever into the modding community and giving them a much larger target audience. Definitely a huge step in the right direction.
Looking at the video below there already seems to be a lot of different and unique maps.
Arcade days with Twelvians might be around the corner?
