Well as it turns out, thankfully, the always-on requirement was not intended. According to a tweet by a Konami representative, they wrote, “We are aware of the offline play issue for Metal Gear Rising for Steam and are working on a fix. Please stay tuned for more updates.” It is unclear if this always-on requirement was intended and Konami are reacting to the negative responses to it by “fixing” it, or if it was added by mistake and they are truly looking into the issue and hopefully have a fix for gamers soon. Either way we guess it looks like Konami will be addressing the problem in the near future, and while the game is playable at the moment, we guess you should probably make sure you have a stable internet connection, lest you find yourself unceremoniously booted from the game mid-play.
