Sega has detailed how the 'Uniloc: SoftAnchor' PC DRM system will work for its upcoming game Alpha Protocol. No need to go mental, its sounds decent.
As Sega explains: "The system will allow the user to activate Alpha Protocol online immediately out of the box and once activated the user never needs to worry about activating again.
"The activation can be used on a limited amount of PCs, and can be deactivated through our online servers allowing the user full control over their license - should they need to re-install, swap machines or suffer a catastrophic hardware failure on their normal PC."
That's much nicer than the militant always-online system Ubisoft is using for its PC titles.
The Sega rep went on to explain: "In the future, SEGA will be releasing an unprotected patch of the game to alleviate any fears of not being able to play the game when the Uniloc servers won't be around anymore. We also do not use Steamworks - the Steam released version will use Uniloc DRM."
