Due to a few game impacting issues that have been brought to our attention in the community, we felt it was best to disable further purchases of the game until we are able to address them. Although we did conduct fairly rigorous testing, clearly we missed out on issues that our fans are seeing, and we feel it appropriate to get them resolved before putting XG2 back up for sale. We apologize for any inconvenience this may have caused you and promise that we will re-enable purchases again as soon as possible, after some of these problems have been addressed.
