If you're confident in your knife skills, go through to the police station without shooting anything. *Dont go back for the shotgun or bowgun as they could get you attacked by a group of zombies* Then, when you get to the police station and go down the stairs into the tunnel, fire everything you got into the zombie you see. He'll drop a special key to use fairly early in the game.
Get the card key and unlock both doors.
I generally go through the large blue doors first; my first goal is always to lower the emergency ladder in the lobby, because you will have to go between floors a lot. My second goal is always to unlock the door in the hallway where birds will break through the windows on your way to the helicopter crash.
If youre familiar with where herbs lie on the map, I suggest leaving them where they are until you need them. If not, be sure to grab and store them. *side note: you want to have a full inventory of full healing items when you reach the final boss.
Be very careful in the lower floors in the jail and past the sewers.
If you plan on playing Claire's senerio after Leon's, leave her something in the armory. (In the first scenario I generally grab the gun because of something I point out later)
After you've left the station and are going through the area where there are 3 so so zombies in every corridor *you'll have noticed the ground shaking above you, etc* (as Leon you'll be with Ada, as Claire you'll be with Sherry), search everything. There is a locker key there in one of the dead end corridors which will unlock a weapons locker in the Umbrella facility later, which will supply custom magnum parts. Claire will also find a Spark Shot, a rather nice weapon.
In the Umbrella facility, go through the blue door first.
When you get to the lower level with the slime all over the walls around a doors, go inside and log onto the computer as GUEST. Do this again on the next senerio to discover a sub machine gun.
Leon will find the flamethrower in the room where you read about security changes, and there will be a plant in the ventilation. I believe Claire will find bolts here.
Make sure you're carrying as many herbs as you can when you reach the final boss. *in the second senerio you'll want to have extras in the storage chest as well, for later.
Good Luck
