Konami's Metal Gear Rising: Revengeance that was released for PC was reportedly not playable offline, because of an always-online bug, NeoGAF and Steam reviews reported.
Konami has confimed that there is an always-online bug and it is not any additional DRM. It said in a tweet that it is working on the issue and trying to fix it. "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!" tweeted Konami.
Further, its developer, Platinum Games has also confirmed of the bug and its creative producer, JP Kellams tweeted, "OK. Getting to the bottom of offline play. It is a bug. It is not supposed to work like that. We are working on a fix and will update soon."
Revengeance was released on 9 January for PC but the excitement of the players was cut short by the bug. The listing does not specify the necessity of an online connection for the game in order to progress.
Many Steam reviewers gave negative reviews to the game due to the presence of an always-online bug.
"Well, the 'DRM' issue seems to have been just a bug with how the game interacts with Steamworks, and hopefully will be addressed in the near future. I'll give Platinum a pass on this one seeing as they might not know much about PC games. That being said, game is still amazing! Although there are a few minor glitches (two cutscenes seem to stutter and freeze, weird anti-gravity glitch affecting props), the game is still a ton of fun to play with great replay value and lots of extras such as costumes, two extra campaigns that allow you to play as bosses from the game (Blade Wolf and Jetstream Sam), VR Missions, and achievments for all the completionists out there!" said Howl who recommended the game on Steam reviews.
"All in all, it was a rocky start to be sure. But MGR is still MGR. Which means you're gonna have fun cutting out dudes spinal cords no matter what," he added.
The always-online DRM caused irritation to many gamers, however most of them enjoyed the game.
