I don't play a lot because I don't want to spoil my game. But all my friends have all the HoE achievements.
How to do it? Easy. Start a 4 wave HoE game. Solo the 4 waves and when Hans come - your friends join. Boom - easy peasy. All of you get the HoE acheavement.
Why they should be wiped? Because KF is the only game where acheavements matter and in KF1 you had to beat a 10 wave HoE game in order to get the achievement.
The game is just really broken at the moment and if you don't care about achievements then why whould it bother you if they do get wiped?
I dont care how others get them (and personally I dont know why people care about others achievement), but I care when they wipe MY PROGRESS.
And I still fail to understand why KF is a game "where achievement matters". Does it give you more damage? Does it make you a pro? Does it make people stop raging scrakes with nades? May be it makes you feel better when nobody get them but you do, but I only care if I achieve my achievements.
