Rumours that Ubisoft's contentious copy-protection method has already been cracked is false, says the publisher.
The piracy prevention method, which requires all Ubisoft PC titles to be constantly connected to the web, has only been available for a day with the US release of submarine sim, Silent Hunter 5.
A pirated version of the game, according to Kotaku, is already doing the rounds on illegal file-sharing websites. But Ubisoft insists this is not a complete version of the title.
"You have probably seen rumors on the web that Assassin's Creed II and Silent Hunter 5 have been cracked," a spokesperson told MCV.
"Please know that this rumor is false and while a pirated version may seem to be complete at start up, any gamer who downloads and plays a cracked version will find that their version is not complete."
Ubisoft defended its controversial solution last month, with UK marketing director Murray Pannell telling MCV:The impact of piracy on the PC market is enormous and working to thwart it is crucial to our future ability to continue developing for this platform."
The DRM solution is set to be used in Ubisoft's upcoming Assassin's Creed II for PC.
