OK, so I'm playing the beta.
Wanted and Manhunt modes are the same, really. There are two new modes - (Easy) Deathmatch, and Artifact Assault.
Easy and regular Deathmatch are on maps that are 1/4th the size of a normal map. No compass, but no duplicates. Easy Deathmatch has no abilities, while you can use them in regular Deathmatch. If your target is in your line of sight, their picture will light up.
Artifact Assault is, essentially, capture the flag. You're a hunter in your half of the map, and a target on the other. Fun, though; I figured out a few good strategies for this one already.
You either need PS Plus or an e-mail invite from Ubisoft to get in.
