No, you can't. DLCs are region specific. So if you buy this version or any other game from other regions beside the US and ended up liking the game, you won't be able to purchase any DLCs for them from the US PSN store.
[quote name='mccurve85']Says its a Region 3 copy (Taiwan, Korea, the Philippines, Indonesia, Hong Kong ). Will it still pull down update to the main game from my Region 1 (US) PS3? Can I download the DLC from the US PS Store?[/QUOTE]
