Solo pro isn't that hard. You can run past most enemies and not even bother. I set all my fastest times on Pro. A ranks for time, accuracy and deaths and D rank for enemies killed haha.
Either that or just take your time, and think about which character you want to play as for each chapter. Some have easier jobs than others. i.e. Jake is far easier in chapter 3.
Go through on normal or amatuer first. Get some skill points and unlock infinite ammo for something (magnum and/or shotgun) as well as the one where your AI partner gives you pills when reviving you. And for Ada's, well it's just a lot easier than the other 3 anyway, but infinite crossbow would help if you have the points.
