Resident Evil 6/Leon Chapter 3

On the way on a bus trip, things turn for the worst in this cutscene: crashing into zombies, a truck and a bus crash near the cliff. What a rotten way to go. Your goal is still have to go to the church so you can catch a breather.

Last time on the bus
With the policeman and a girl, overwhelmed by zombies, you'll be on the ground, on your back so shoot as many as you can before the bus falls off the cliff. When that happens, all the survivors on the bus died. So, there's little choice but to move on.

Silent graveyard
If your GPS is automatically on, you just follow the path, knocking zombies out of the way until you reach the gate entrance. But, you need a key to open it. So go check inside the house on the right of the entrance. When you reach a locked door, shoot the lock open and go in, only to see a dog with the key running out. Great! So continue your search through the graveyard until you find the dog with the key.

So, once you found the key, make your way back to the gate entrance. As you walk through it, Leon, falls off with a zombie attacking him. It's far from over since Leon and Helena get separated. So if you're Leon, you have to get all the way back to the gate entrance while has Helena, you should go to Leon first before going to the gate entrance.

Church entrance fight
Leon and Helena tries to get in but to no avail. So fight as many as you can and break the remaining crates as your ammo supply might just run out. When the sniper comes out, that means the fight is nearly finished. Continue until someone inside gives in. You'll see a cutscene of the inside of the church.

Church puzzle breather
Now that's out of the way, you can save your strength to do this crazy puzzle. After checking the back end of the church, this is the time for puzzle solving. Grab the statue on the right side. Then check the bottom floor for the statue. Then the top. But you need Helena to get the ladder down. After that, check the top floor for the statue before setting both statues on both sides just to open the door.

Statues and sunlight
Now go down to the unlocked door for some more puzzles. The first both rooms is just pressing a button on a statue so it can retract itself. Do the same, several times on the next room. Watch out for more zombies on the way. Grab the statue after the statue puzzle and go upstairs to grab a sniper rifle. The next part is kind of tricky. Try to shoot the five bells towers on both sides. Two of them involves small bells with the roosters which is tricky so zoom in some more and time your shots. Should you run out of ammo, grab some more but if you can't, lose the grenades and remote bombs and even make more health items before grabbing more sniper ammo.
