The free running options are new to me since I didn't play Unity. I'm still trying to get use to those, I tend to frustrated when I can't jump off a simple ledge and realize that I have to hit circle to drop down a whole 2 feet.
I'm at level 4 for both Jacob and Evie. I'm using the kukri for Jacob and the cane for Evie as well. I was defending my train in a fight last night using Evie and while beating up two blighters, one was stunned behind me and I was beating up another in front and I pummeled the one in front of me and in a quick little cinematic, she threw the sword part of the cane into the head of the one behind that was stunned, finished off the one in front and then turned around with the rest of the cane and cracked the other guy across the face. It was freaking awesome to watch.
I've only done one crime solving case and that was the one in the first Burrough but I did like it and will learn to pay a lot more attention to everything that goes on during those.
