By now, it should be apparent that Sam Fisher is no one to be trifled with. We've watched him slamming heads against toilets and executing hapless henchmen for some time now, but maybe there are still a few people out there that don't quite get it. Obviously aware of this problem, Ubisoft has released a launch trailer for Splinter Cell: Conviction that should make things perfectly clear. With a little help from Johnny Cash, the trailer pretty much spells it out: Mess with Sam Fisher and, sooner or later, he will cut you down.

Watch the trailer. Watch, and wait.
