Got this information yesterday. Blizzard Entertainment is letting out some good news. From 19th November to 21st November (Singapore time), gamers can experience Starcraft II over Battle.net free of charge.
Blizzard Entertainment today announced that there will be a free-play weekend for the Southeast Asian edition of StarCraft® II: Wings of Liberty™. From 00:00 on November 19 (GMT +8) to 23:59 on November 21, gamers throughout Southeast Asia will be able to experience StarCraft II’s award-winning single-player and multiplayer gameplay over Battle.net free of charge.
New players who would like to participate can create Battle.net accounts at https://sea.battle.net/account/creation/tos.html and activate StarCraft II on their accounts. Players with existing Battle.net accounts which do not have StarCraft II are also welcome to participate. Note that an internet connection is required to play or simply visit your nearest internet gaming room with StarCraft II installed.
The free-play weekend kicks off the availability of the recently announced StarCraft II prepaid game card options for players in Hong Kong/Macau, Indonesia, Malaysia, the Philippines, Singapore, and Thailand. These game-time cards come in 3-day, 7-day, and 30-day increments and offer players flexible payment options to suit their preferences.
