That was GM1 which is zero fun in epic gear thanks to enemies being huge bullet sponges and their ability to one shot you with zero warning
Even on hard certain enemies can burst you to death in a matter of seconds but they're not so spongy so it's tolerable, the only problem is less chances at the fewer MW items but it's more fun than trying to struggle through GM1
However getting zero reward for a total of around 9 hours over the past 3 days makes me question what the point in it is and whether I should just uninstall which would be quicker than a loading screen
