Sonic Mania on PC has Denuvo, always online requirement

3 min read


We live in a weird time, where sonic is actually good again. Sonic Mania is a return to glory for the blitzing blue speedster, with many fans and critics applauding the game’s superlative level design and back-to-basics approach. It’s also stuffed with fan-service, memes, and other little pop culture nods that show that SEGA’s not taking itself, or Sonic, too seriously.

The game is finally out on PC – but many people have discovered a problem. The game’s been saddled with Denuvo’s anti-tamper tech, which isn’t really a problem in itself. What is though, is its implementation, that requires that the game be online to play.


The game won’t unlock or launch if Steam is set to offline mode, which means that if you want to play it on the go you’ll have to boot the game while connected to the internet and leave it running in the background while you step away from Wi-Fi access.

SEGA is aware of the situation, and plans to fix it. As per the game’s Steam page:

“Like you, we’ve noticed an error in the Steam store not mentioning the DRM for Sonic Mania.

We’re fixing that now.

Sonic Mania is intended to be played offline and we’re investigating reports on that.

We’re also investigating other issues like controller support, these are all PC specific things that Christian and the team have been working on these last few weeks

Please bare with us while we collate and investigate problems that are being brought to our attention”

Sonic the Hedgehog’s PR chap Aaron Webber took to Twitter to urge fans to let SEGA know of their displeasure.

While I will always champion developers’ rights to protect their copyrights, the inclusion of Denuvo is a strange one. The game is hugely anticipated and affordable enough – and including Denuvo destroys much of the game’s good will. According to reports, the PC version otherwise runs well, and includes a few fixes not yet found in the console versions.

Editor. I'm old, grumpy and more than just a little cynical. One day, I found myself in possession of a NES, and a copy of Super Mario Bros 3. It was that game that made me realise that games were more than just toys to idly while away time - they were capable of being masterpieces. I'm here now, looking for more of those masterpieces.
