Since I'm only an hour in: nothing, really.
That might change later on.
- Your gauntlet has charges. These recharge over time, or you can pick up items to charge them. It's not something I'm actively monitoring, and that works fine.
- You can only throw your shield so often, but it recharges so quickly that it doesn't matter.You can only block so much with your shield, but that is pretty irrelevant as you shouldn't be blocking but parrying and shield bashing. The shield bash is also on a cooldown, but it's really quick. The shield doesn't use gasoline and the like.
- I honestly have not thought about ammo once in my first hour (in contrast to Eternal...).
- Glory kills give extra health, but so far I have always found plenty of health pickups on the battlefield.
So far, I'd say they work more with cooldowns that are relatively short instead of active ressource management of ammo, health, fuel etc. I mean, that is still there to an extent, but not as in your face as in Eternal. In Eternal, you literally die if you don't keep on top of ressource management.
I think people saying that this has more management going on than 2016 simply stems from the idea, that you have many more gameplay options, which automatically invokes "clutter" and ressource management. But as I said, so far it's not really in your face like Eternal.
