Then why make a thread about it? Making demands will get you nowhere.
I understand can be frustrating if you’re new to the game and not used to how it works. The save system works fine, your progress is saved everytime you move something in your inventory, complete missions, unlock a safehouse and so on.
But this feels like it’s less about improving the save feature and more about planning your fights.
Always make sure you’ve got the upper hand before you engage with Machines. Lay an ambush, or fight from safe distances, where there’s cover.
Use Adrenaline Shots, or draw Machines towards areas where safehouses are close by to save you from running back. It’s a hostile world out there, so remember to come prepared, and like the others have said; don’t be afraid to run if the fight gets too bad.
