Recommended to first acquire the Chicago sweeper by getting an A rank or higher in SW Professional Mode ( to make S Easier )

Proffesional S Requirements: - New Game File - time should be under 2hrs 30 mins - only 10 saves or less are allowed

Tips: Avoid normal enemy encounters as much as possible to save ammunition for Bosses until you get the infinite ammo upgrade for the Chicago sweeper ( which you should get by chapter 4 after the maze section ).

Chapter 1: don't be afraid to unload all your bullets on the black robe it is necessary to defeat it. Watch out for its clones on phase 2. If possible rush all the way to the end of the chapter if not you can kill the enemies slowly and get some treasures. Also don't forget to pickup the sniper rifle and scope!

Chapter 2: don't forget to complete the first merchant quest ( necessary for getting the upgrade ticket ). stealth kill the first wave of enemies then just rush through the rest to get to the next section. Ignore the enemies that came from the village and go up to the merchant immediately. You can upgrade the Handgun and or tmp here to increase its damage. Again don't be afraid to unload your bullets against the black robe while carefully dodging its attacks and clones from the later phases.

Chapter 3: don't forget to do the merchant request!. Run away from Mendez while getting the treasures within the house. If you can save a flash grenade save it. While escaping the area where you get the crossbow before turning the crank use the flash grenade to stun the enemies just enough for you to escape. Again just run away from the enemies in the family while getting supplies because there will be an upcoming boss fight ( El Gigante ).

Chapter 4: one of the tricky chapters because of the plaga knights. Again as per usual run away from unnecessary enemies while getting supplies. For the first part with Luis just run away from the enemies to trigger the cutscene of the burning lab, then you'll both go your separate ways ( XD ). Get the 1st ingredient, then comes the hard part the plaga knights.

For the first batch of plaga knights you can avoid them, but the ones where you get the gild bottle are mandatory so take heed and kill them as carefully as possible while avoiding getting hit from the other knights and cultists archer. ( when you defeat plaga knights you can get spinels which can be used to trade at the merchant ). Next up is the maze ( don't forget to dot he merchant request here so that you can finally get the exclusive upgrade ticket from the merchant ). Killing the black robed cultists here are optional, but killing the red robed cultists is mandatory to move on to the next room. After the maze buy the exclusive upgrade ticket then you're set for the whole game because of the infinite ammo weapon Chicago Sweeper.

Chapter 5: 2 mini boss fights and 1 main boss fight against U3 ( 2 phases ). Purchase a rocket launcher from the merchant to easily kill the 2 garradors don't worry about other weapons because you have the Chicago sweeper just spam. The important part is that you have to kill the 2 garaddors at the same time to make the fight easier and to not spawn additional mobs.

To guarantee a kill for the 2 garradors aim at the floor at the middle of the 2 to kill them at the same time. For the U3 fight just spam the Chicago sweeper while carefully avoiding the boss' attacks. After you successfully kill the boss just breeze through the chapter and your done.

Chapter 6: not much can be said about this chapter because of the Chicago sweeper. Just do what you do in a normal playthrough while avoiding/killing the enemies. Maybe so few tips regarding the fight against regenerators ( you don't have to kill them to progress, just shoot their legs and run ). Flash grenades are very useful too to help you avoid and stun enemies.

Chapter 7: Final Chapter Finally! As per usual avoid avoidable fights then it's saddler time! To make the fight easier and faster again you have to buy a rocket launcher from the merchant again. After the saddler fight just run and gun and avoid enemies to the best of your abilities to help leon! Good luck!

Addition tips: - Don't forget to do the first 3 merchant quests other succeeding merchant quests are optional for this specific guide - stock up on flash grenades as much as possible to make running away from hordes of enemies bearable - if you have treasures on the way or can be picked up with little detours go for them because ptas are essential for upgrades. - for this guide the 2 rocket launchers ( 1 for double garador and 1 for the saddler boss fight ) are mandatory because of time constraints. - practice your routing for pickup up ammo and or avoiding enemies. - If you die don't press continue or load game, quit the game the from there load your latest save file so the time doesn't add up from your death. - Remember you can only do 10 saves for this S Pro mode run so use them wisely. I Reccomend you do 1 save per new chapter but it's entirely up to you!
