has picture with blitzkrieg still lost it XD

I would like to ask your help in the Left 4 Dead 2’ achievements. They won’t take long.
I already have three helping hands in there, but we need more for;

STRENGTH IN NUMBERS
Form a team and beat an enemy team in 4v4 Versus or Scavenge.
(it needs eight players, including me)

CHAOS GENERATOR
Have all 3 generators running at once in "The Sacrifice" finale.
(it needs three players)

SACRIFIZZLE
As a Special Infected, incap someone who is trying to sacrifice themselves.
(it needs at least two players, but it would be easier with more players whose don’t attack the survivor)

Please leave a comment on my Steam profile and let’s help each other.
Thank you in advance.
Sincerely, Atlaimond
