Did anyone here manage to get all the achievements?

I have 65 of the 70. Those last five... I don't think I'll ever get them. But who knows.

For a while, I was obsessed with Scavenge. That's all I would play. So I got a lot of achievements for it.
As for tips... form a good team and play many rounds.
But most importantly: have fun. I got those achievements just enjoying my time playing.

You'll get them. I know it. :)
