I’m just finishing my second play through on PS4. That would be a tough speed run. I wonder how long it would take me to run through the whole game again just doing missions and wasteland missions... I’d have to haul ass and clear each area as fast as possible. Upgrades for the jacket and shotgun are out since I can’t use them. It would definitely take a little while. Getting car upgrades won’t be easy since the game doesn’t just give you lots of scrap. You have to earn it gradually.

It would be hard. Not having to do wasteland encounters in all missions is good though. I've learned your car is definitely not required to be heavily pimped to do the missions.

Mostly not pimped. You would need max thunderpoon for the gas town race. You could probably get by with medium armor on your car since the heavy armor is no good at that race anyway. And you can’t use your shotgun or upgrade your jacket which makes things double tough. But you can upgrade your legend which means you would really have to do a play through to see what you could live without when it came right down to living or getting killed.

Since it's now split into NG/NG+ categories. I've managed to get both All Missions categories in under 4h 20m's. Would you believe I actually cut a full hour compared to my first runs?

My new record run(once verified but it's on my twitch and youtube) for All Missions NG is 3h 54m 56s. That's right, I got it to under 4 hours
