In Ghost Mode, two players are dropped onto a map and given the same target to eliminate. The first player to earn five kills wins. But things aren’t as straightforward as all that sounds. In the mode, players will indeed be on identical maps, but they won’t be in each other’s world. In other words, neither player will have a direct impact on what’s happening to the other player. However, similar to games like Dark Souls, you will absolutely be able to see the other player’s “ghost,” a pretty terrifying monochromatic version of Agent 47. Your opponents will be visible at all times, so you’ll be able to see exactly how they’re going after the target, or you can be more strategic and try to come up with your own, faster path to the prize. The image at the top of this story does a good job of illustrating this fact. In it, you see both versions of Agent 47 taking out the same target. But while the player in the foreground is trying to strangle his prey, the Ghost character has already finished the job with a silenced pistol he picked up along the way.
