Text and Video guide to help you unlock the achievement if you haven’t yet. Hope this helps!
 
 

Double Check Your Settings

You want to start off by opening the settings and opening the “Controls” tab, you will unplug ANY controller that could be used for Player 2 until the Controller Type reads “NONE”. This way once you load the game it won’t activate a second player til you want it mid-game.
 
 

 
 
 

Start A New Campaign

You will want to open a New Campaign with Cooperative Multiplayer, remember that we currently do not have a second controller so when you hit PLAY you’ll be alone,
 
 

 
======================================================
 
if you hit the loading screen and you’re asked to press SHOOT to ready on 2 controllers, you will have to start over.
 
 

 
======================================================
 
When you load into the game you will be alone.
 
 

 
======================================================
 
After the first enemy, plug in a controller of any kind and hit start.
 
 

 
 

 
======================================================
 
At this point you should have the achievement! Hope this guide was easy to follow and VERY clear. Happy Hunting!
