I'm trying to find a save point after the fight with the robo arms (chapter 6, I think) it took me like a hour to beat those arms (and flames) I had no supplies I was almost dead and they wanted me to survive though a train station.....I promptly died. So now I have to kill the robo arms again. but i'm not gonna even try it until I know where to go after to save. anyone know a site with a map of the toilets? I've looked online but found nothing.

Yeah, i did not save before a battle with some boss and had to re do everything before, but that's what i signed up for when going nightmare also i like playing the game. I have not found alot of the save porta potties but clearing out safe houses helps a lot since they are at least on the map. Doubt there will be complete maps out there since it just came out.

When you finish the robo-arm boss battle, you end up just outside the factory in South Almuda, in front of the Los Perdidos River. Run down into the river, keep your eye to the left. You'll see a cement truck parked between the feet of the overpass above, and behind it, tucked out of sight, is a porta-potty save point.

just recorded a GDVR clip, it may be listed under my Gamertag, Ventil, Help & Tips, "post robobattle save"
