We apologize to our Resident Evil Revelations 2 PC players who purchased the game and expected to have local co-op as a feature. The feature wasn’t intended for this version and that caveat was mistakenly omitted from the product description on the Steam page earlier, and then included as soon as we were made aware. This was an unintentional error and again, we apologize for the confusion this may have caused.
We are currently looking into the matter and potential solutions and we hope to have new information to share very soon, so please stay tuned. Thank you for your patience and understanding.
