Item description:

How to beat Train Birkin in Scenario 2B on save slot 3
Spoiler:

Save Slot 3: Claire Scenario 2B Standard S Rank with No Item box uses / No first Aid uses -- Modified this so it will be super easy for players to use after I beat it.
---------------------------------------------------------------------------------------------------------------------Use the Sparkshot all 7 times after Birkins gets into the Train Car. Then swap to Grenade Launcher
-------------------------------------------------------------------------------------------------------------------------------fire the shot, then to your sub machine gun and unload, and finally to the pistol and fire a few.
------------------------------------------------------------------------------------------------------------------------------------------He will get in your face and almost kill you so be quick and get those shots off.

Please note S+ Rank is done by the following
Do Not Save More than 3 Times Total - This can be fixed with Save Wizard
Do Not Touch any Infinite Weapons - This is a must


Here are the times to get S+ or S depending on Saves, deaths, and Infinite Weapons used (S+ aim for no deaths if you die just quit to the main menu and reload.)
Leon A (Standard): 3 hours 30 minutes Leon B (Standard): 3 hours
Claire A (Standard): 3 hours 30 minutes Claire B (Standard): 3 hours

Leon A (Hardcore): 2 hours 30 minutes Leon B (Hardcore): 2 hours
Claire A (Hardcore): 2 hours 30 minutes Claire B (Hardcore): 2 hours.
