Sam Fisher is a man of many talents, and as we all know, there's never only one way to deal with a situation when you're a trained killer like he is. The latest Splinter Cell: Blacklist trailer, we get to see how player freedoms work. The game gives three main options in dealing with any situation: Ghost, Panther, and Assault.
Ghost, as the name pretty much suggests, is the all-stealth path, where you sneak around and don't enter confrontations unless you absolutely need to. Panther is a variant of that, where you still sneak but also take out enemies as you go -- just in a very sneaky way. Assault, on the other hand, is that Call of Duty-esque method of approach, where you attack enemies head on with everything in your arsenal.
Hey, something people like the direct approach. I'll probably be going Panther, myself.
