This is mental. I'm shootdodging more now that I'm playing Hard and I've not died once. Chapter 3 now. I know it's easy goings in the first few chapters, but now that I've gotten used to Max's new move set, I know when to shootdodge, when to roll, when to take cover, and so on.
Painkillers also fully heal you in Hard, which is awesome! I find they're much more plentiful now as well. I finished the Moderno rooftops with 6 PKs. That's more than I ever had in the entirety of my Medium playthough.
I've found that you can roll out of cover, and then chain that into a shoot dodge, which is very helpful.
For instance, in cover, point out of cover, double tap sprint to roll out of cover, and then in the middle of the roll, tap shootdodge and Max will transition straight into a shootdodge (in the direction that you were pressing the stick in the roll) which makes moving around much safer.
I'm blown away. This game is almost playing better now, on the Harder difficulty. It probably has a lot to do with the fact that I know when and where enemies are coming from, but still. I've mastered the controls and Free Aim is really showing how much more of a badass you can be when you take the training wheels off. I used Free Aim on my first playthrough, but now that headshots are even more important, I can see how someone starting on Hard with any assits would find this game to be really, really hard.
