Official statement: September 19, 2012:
2K Games and 1C Company have updated the PC versions of Borderlands 2 that are purchased from both retail locations and via digital distribution in Russia, the Baltic states, and CIS territories. Consumers in these countries will now receive a bundle that contains both the 1C Russian language version of Borderlands 2, as well as the 2K Games worldwide (English, French, Spanish, Italian, German, and Japanese) version of the game. This gives consumers in these countries the widest range of options to both choose their preferred language and play with their friends across the world.
Though the 1C and 2K versions do not support cross-version play, consumers can install both versions and have the option to play each. Additionally, Borderlands 2 Season Pass and DLC content purchased in these territories will contain this bundled format content. We thank customers for their feedback as we continue to work to provide the best products we can offer worldwide.
2K Games and 1C are aware that digital distribution pages for the Russian, CIS and Baltic States versions of Borderlands 2 contained incorrect information regarding the language and cross territory compatibility support. We apologize that this information was incorrect during the pre-sale and pre-order period for these territories. We are working with our partners to update those pages, and offer any customers who pre-ordered or pre-purchased the game the opportunity to cancel their order and receive a refund.
Additionally, we are working with our product development teams to investigate potential support for additional languages and options for our customers in these territories. While this was and is not possible for launch, we will provide an update this week on our progress.
