Nice work on the regional price rorting, $50 for US customers, $80 for Aussies and an embarrassing $100 for New Zealand customers, was looking forward to some co-op on this thing - but there is no way in hell I'll be parting with $400 for a four-pack.
If anyone knows where I can buy legit copies (no russian key sites thanks, my steam accounts are far too valuable to risk) without being asked to pay double the US price then please let me know.
