For me, I've stopped focusing on where I'm dropping in. I don't bother trying to get to a specific house or anything. I just dive towards the ground as fast as I can. Its risky, but I find that just landing in the middle of nowhere, away from all the structures and picking your way through those little out house looking buildings can lead to long runs.
I also try to keep my way point at the center of the circle. I don't necessarily go straight for it, but it keeps me headed in directions so that I don't get caught outside in the blue.
Lastly, I stopped worrying about red zones. Sure you might get hit, but running straight through and storming into buildings is a good way to get kills on people who are waiting out the bombs. Just keep your cross hairs trained low and do a quick lean around corners to see if someone takes a pot shot.
So far playing it has been fine. It's fun to shoot, explore, and jump jet around. The story though... could either really get interesting or completely flounder. So far I feel like everything past the prologue has been massive exposition dumps between characters who seem slightly annoyed with each other even though I'm trying to be a nice guy to everyone. Be interested to see the reviews in the am.
My strategy was dashing all the time. I'd hop in and get a few quick attacks with mid spear and then back off and dance around him. Also it helps to go in with a charged guardian so that you can break the ball and chains from him quick. His second phase is much easier as he telegraphs everything
Having finished the game as Emily. The one thing that I can give this game without question is that there are a lot of strong female characters. Nice to see that they took a lot of the influence from the previous game's dlc from a character stand point. That said, the story is way to similar to the first one. I wonder if they had kept the working title "Black Sparrow" instead of making it Dishonored 2 if they could've changed story set up to be a little less like the first game. Minor story quibbles aside, this game is still the most fun you can have with stealth and the art direction continues to be breathtaking.
