I've heard a lot of negative feedback lately on regenerating health in modern shooters, and for some reason, it made me think of Ninja Gaiden II's health system. For those of you who don't know, how it works is that you have a health bar that regenerates after a fight, but some of the damage you take becomes lasting damage, slowly decreasing your maximum health, and when you reach a checkpoint, your health restores fully. So I was thinking, could this work in a shooter? I think it could, but I'd like to hear other perspectives as well on this.
