In Ghost mode two players compete to be first to silently assassinate a target. The other player is always visible, so you can see what he’s up to and how close he’s getting, but he actually exists in his own instance of the game. Anything he does to his own NPCs won’t affect those in your game. When one player makes a kill without being spotted, the other gets 20 seconds to repeat the feat, otherwise a point is awarded. First to five wins; it’s best played with an actual friend to minimise rage-quitting.
