Just fixed my post. I forgot to mentioned that I'm playing with my friends online in custom games.
chanbrothers, I bought it from Tec-Drome Pte Ltd at Sim Lim Square.
See here if you need help getting there: http://www.simlimsquare.com.sg/stores_floor/l5?page=5
Be warned though, since it's an import, the prices are about SGD$75. I bought four copies together with my friends and got a goodwill discount such that each copy became SGD$68. Don't quote me on this though, I can't guarantee he'll repeat that feat of generosity.
If you really don't wish to buy from them for whatever reasons, just wait till 15th May for it's launch in Singapore or purchase online from Impulse. For me, I simply wanted it NAOW and wanted a physical disc instead of simply a digital download hehe.
EDIT: Just in case, they do NOT have the collectors edition, which I wanted but settled for a normal copy.
