Multiple day-one purchasers of Splinter Cell: Conviction are seeing the game freeze on its second level and at other moments. Publisher Ubisoft tells Kotaku the issue is being investigated. Please note: There is a temporary fix. [UPDATE: Ubisoft resolves problem?]
The freeze has been reported by Xbox 360 players who have been playing the game with an Xbox Live connection. They reach the game's second level and it freezes. (The example above is from Kotaku reader SanjiX).
UPDATE: A Ubisoft representative tells Kotaku that the game should now work fine: "The issue has been resolved, you should now be able to play without further problems. You can download the update now and be able to play the game without it freezing or needing to be unplugged from Xbox Live."
Some of those players, according to comments published under Kotaku's review of Splinter Cell Conviction, say that clearing their 360's harddrive cache and then re-booting their 360, with Xbox Live disconnected, allows them to bypass the freeze.
