Okay, so let's say you're getting your ass handed to you in Bloodborne (don't worry, it's a common thing).
If you want to team up, or if you'd rather hone your skills against human players, check out a detailed post over at the PlayStation Blog .
It guides you through the available multiplayer options and offers some helpful hints if you're new to the experience. Remember, Bloodborne offers both cooperative and versus online multiplayer fun, so feel free to experiement. Up to three players can enjoy the game together and the blog post shows how to initiate such a session. If you didn't already know, you need the Beckoning Bell if you want to play Host to other willing players.
They also explain how multiplayer works within Chalice Dungeons, which is good to know for all you advanced players out there. Would you consider yourself "advanced?" Or are you still plugging away, just hoping to survive?
