Bloodborne is out now and while it's certainly a hard game, there are some things you can do to make the experience a little easier.
A Redditor has put together a guide on farming blood vials and bullets. Using the method listed below, you can pick up10 to 15 blood vials and 12 to 15 quicksilver bullets.
"Start at the Central Yarnham lamppost and run the route you'd normally run as if it were a new game. Just power through all the trash collecting vials, and make sure you don't miss a firearm wielding dude, they almost always drop bullets. Just kill everything.
"Once you hit the bridge with the 2 werewolves (as a bonus they sometimes drop a bloodstone shard), kill them and take the left into the unlit house, kill the 2 guys upstairs, run downstairs and take the 2 downstairs out. The wheelchair enemy seems to always drop 4 bullets. Head out the door, up the stairs and back to the lamp post, through the short cut gate.
"This will net you around 10-15 vials and bullets along with 3000ish blood echoes. Once you get the route down you can run it in less than 5 minutes, and completely stock up your storage bin with vials and bullets, and use the blood for whatever."
