The status of retail distribution for Sentinel's Fate at launch internationally is still uncertain. However in an effort to properly serve our international community we have partnered with several digital distributors who will be providing the expansion to our international customers only starting on Feb 16th 2010. The digital downloads will be IP locked so that only the international community can take advantage of this.

Any discussion will be directed to this thread if you please.

Thank you.
