The newest trailer for Splinter Cell Blacklist features 3 play styles that the developers encourage while playing the game, Ghost, Panther, and Assault. Just hearing the names you probably already know what each of them represent. Assault encourages players to "leave no witnesses behind". The first 30 seconds of the trailer say "Do you think you know Splinter Cell? Think again". Yet, it seems the developers themselves don't know Splinter Cell.
Splinter Cell used to be king of the stealth genre, with incredible stealth mechanics like the visibility and sound meter, intelligent AI, and having to actually be stealthy. I remember a lot of missions just outright failing if I ever popped off a shot. Now Splinter Cell is a shining example of what not to do with a good franchise. By making the AI into ass, simplifying the stealth, and even give players an auto aim feature, I've lost all hope for a good Splinter Cell game any time soon.
