Joystiq reports the wonderful news that Prey is deliciously region free. That's right, any copy of Prey from anywhere will play in any old 360 you happen to have lying around. As an added bonus -- and this is the real reason for this post -- you can pick up the heavily discounted Asian version from Play-Asia for $40 US plus shipping.
See? Sometimes there are advantages to the 360's abysmal performance in the Asian market.
