Complete the Game - It’s a good idea to finish the game before attempting an S-Rank run, so you know your way around Raccoon City.
Practice - If you find yourself struggling to finish the game with the S-Rank time limit, keep trying again and again, shaving off a little more time every run.
Acquire the Infinite Rocker Launcher - Before jumping into an S-Rank Run, you may want to consider farming up 62,400P for the Infinite Rocker Launcher, as this will make you run go alot smoother.
Retun to the Title Screen - If you die during your S-Rank run, you’ll want to return to the Title Screen, as hitting continue will waste more time whereas reloading the save resets it.
Practice Dodging - The easiest way to bag an S-Rank is to Dodge past most of the encounters you face, so you may want to spend a while in an easier difficulty learning how to time it perfectly.

Tips and Advice (Inferno)
Once you’ve beaten the game on Hardcore/Nightmare and got an S-Rank on Standard, you’ll now have the option to play the game once more on Inferno to get another S-Rank. However, this is a lot easier then you may think, as if you have the Infinite Rocket Launcher unlocked you’ll be able to destroy every enemy/boss with no problem at all.
The only major difference you’ll need to worry about on this difficulty is the disabled Autosave. To deal with this, you’ll want to do a run through the game to refresh your mind on where the boss battles take place, so you know when to do a hard save on your S-Rank run. For example, Demolition Site Rooftop is a great place to save your game as it’s right before the very first Nemesis battle.
