which is a better play style for multiplayer? quietly sneaking through crowds of people or runnin and gunnin across the roof tops
Your goal isn't merely getting all the kills you can, but rather racking points up from how well you perform your kills, escaping from pursuers, and humiliating them. You need a balance of speed and stealth.
I'm really not very good at wanted mode (free for all), but I rarely play it. I spend most of my time playing manhunt. Manhunt is a 4 vs 4 game type where two teams take turns playing the hunters and the hunted. The first half of the game, one team must hide the best they can from the other team. The offensive team must be careful because they have to figure out which character they must kill and try not to kill an innocent civilian. They must also be careful not to get knocked out. After the first round is over, team 2 goes on the offense and team 1 must hide.
You really do have an advantage when you use team work. You want to stick close to your buddies so when one of you is assassinated, your team mate can humiliate the guy who killed you. Same when you switch assassinate and humiliate around. After each attack, you go through a moment of vulnerability. This is why it's nice to have a team mate nearby.
I have a problem with team mates rushing too quickly. I'll be blended into a crowd of people, waiting for my target to walk past me so I can stealth assassinate them and get somewhere between 300 and 600 points. Then, I'll see one of my teammates run up to the guy and kill him for a lousy 100 or 200 points because he didn't want to be stealthy. This is why it's nice to play with friends who have mics and can cooperate well. It's also easier to find other groups to play with online (shorter wait times), but that's only if someone isn't kicked from the party for who knows why. : /
