First of all you want to launch the game, using steam press play. After viewing the "scary" splash intro screens you are into the title menu. As per usual being part of the PC master race you would want to jump into the video setting and alter it to your computer preferences (for my GTX 780 i just maxed everything i could and turned Vsync off). You should be feeling good that your are ready to jump into your first match.

For this section its about how to get into game quickly (well the fastest possible) You should have some friends who also want to try out this game get them together and into a group of 4 (since the 5th slot is currently broken by saying the lobby is full) But if you are unable to find any friends who have the game or want to play with your because you bought them a copy of bad rats ;( You have 2 options; Become ultimatly bored for atleast an hour OR comment in the comment section below and add some people who are willing to join you to make the waiting time from 1 hour solo to average of 25 minutes.

There are a few errors i have recently run into, for example

"Networking Errors" To try and fix this i restarted my game and was able to join a players matchmaking lobby

"Matchmaking is full" This errors occurs when a 5th player tries to join the game, this is because as a party you're unable to become the monster so it is not a viable slot.

I have not encountered any other bugs in the game as of this current time.

Now you're in a lobby with your friends/random people. You need to understand this game has just came out so the servers will be terrible like other games, Destiny, arche age for example, to pass the time you could watch a livestream of the game to get the feel for it before you play or you could just have some fun with your friends. For me the game didnt take long to get into a match probally 3 minutes at the most so it isnt the end of the world. Enjoy!

Quick note : Once you get into this game you will love it, its amazing in many aspects and challanging at times!
