By the way, what happens if Desmond stays outside for more then 10 mins?
I have no idea. You should really try the multiplayer as soon as you can though.
The first day the game came out, it was hard to get into matches in multiplayer. I probably said this already, but if not, they fixed that problem for the most part. Once in a while you get into a semi lengthy wait, but that's about it.
I don't really care for wanted mode, but when you play manhunt, it really helps to team up with people you are comfortable talking to and it helps even more to be able to follow each other's advice and commands.
This is a good example of team work. Player 1 has the perk called Templar Vision, which allows you to spot your targets (they become blue). Player two have the perks disguise and poison. Disguise allows them to change their skin while poison kills the enemy slowly, bit gives massive amounts of points.
Let's say one of the targets on the other team is a prowler, and they use the morph ability in a small crowd of people. Morph transforms everyone around you so they all have the same skin. Basically, you end up with 6 identical prowlers. Player 1 uses Templar Vision to spot the real target and marks him. player 2 can also see this mark and uses disguise so he can walk up more safely to the target without the target humiliating him or throwing a smoke bomb. Player 2 walks past the target, using poison, and walks away. Before the target can react, he dies. Player 1 gets a few points for co-op kill, player 2 gets a lot of points for being stealthy and using poison. The team, as a whole, gains a lot of points.
Remember, one good kill can earn you points that equal six poor kills.
