I didn't get that much time to balance ammo pickup spawn, so sorry about that. I guess I didn't find a sweet spot for that backstory text either. An issue I had with ammo was getting it into the gun I wanted, so that would be something that I would be something I would focus on for the full version. Shotgun shots counting as 3 ammo was there because that's how they work in real life so I didn't see anything too problematic with doing that. I might thinking about changing that in the full version, but I'm not sure. I think ammo re-balancing would be a better fix.
