Is there a mod or hack I can do to use quicksaves? I know I can bind a save and load function but that always just saves game state but moves me back to the nearest checkpoint. This can be annoying as enemies respawn if I do that, but I still don't get back any ammo I lost.

If I can't just straight up quicksave, is there at least a way to remove the enemy respawning? That way I can kill all the enemies in an area and then explore without expending all my ammo in the level.
