To do nothing you have to start off with creating your own, or joining a pre-made scenario. Once you get into your battle and deploy yourself, preferable with the enemy team having as much firepower and men as physically possible to increase your odds of doing nothing! Now that you've done that, your going to die a few times, that's fine. Keep your head up and keep deploying in to the fight, don't let them discourage you from your almighty quest of doing nothing.

If you struggle in nothing, keep trying.
If you get tired of kicking the bucket, maybe you can ask someone in the discord for help.
