I'd really like to see a slider/text box for many of these gameplay settings. Getting to choose only between "Off/Low/Medium/High" isn't ideal.
(Mostly cause I'm struggling to do much of anything with enemy spawning set to Low, and I don't want to turn enemies OFF cause then what's the point of any of the gear upgrades? Also, is Low still supposed to spawn like 5-6 gunmen in one area? That seems excessive.)
