I played for an hour, so another 5 or 6 games. It's still awesome. I really like it when you stay alive as a Legend and make it to the final 10, then you have to find the other survivors or triangulate on a point where you can help each other. I didn't quite get it the first time, and I was in a room by the tunnels and we all congregated there. It was like a classic zombie movie. In the matches I played, I think the Legends won more than the Shadows. One match there was 1 survivor, another 2, and another 6. I think this mode will inspire new team play. I kinda wish there was a mode where you started as part of a 10-player team and you fought Shadows the whole time, because that's more fun than hunting Legends and then hunting Shadows. I like the idea of dropping solo and having to find your teammates. The whole map looks epic at night. I love the giant behemoths glowing green, and the one that bellows emits a big cloud of green. Pathfinder does seem to be the preferred Legend. One Shadows win I think there were 15 Pathfinders, it was hilarious.
Anyway, this mode is super fun. It's a great Halloween event.
