Dude! You respawn with full ammo but there are no ammo drops from enemies. Would not work for a mission with a boss fight, but basic missions (Hanging By a Thread as a go-to answer) would be crazy intense. Maybe no time limit then? Raiders would have to really roll slow and be a coordinated group of bad mother (shut your mouth). I mean, there'd have to be other tweaks, but I think the idea has weight, yeah? No? Potato?
