Have some advice - The fact you come into levels full of people with a better weapon than you is insane, have some level system maybe. The minimap hides players in that corner, add some transparency. The game is really dark! I can barely see in many areas. The game offers no explanation for how to play; being shot at without understanding of teams or goals is very confusing.
I cannot find the campaign level "Hat Factory". All I can find is strange spin-offs. I came back to try for the achievement but it would appear I can never get the chance to try it again.
