Been checking out a few video's on Vermintide 2 and I'm liking what I see.. Look's like a good blat of fun. Currently $30USD on Steam.
It can be very involved and highly in-depth at harder difficulties requiring an insane amount of team work.
The video that convinced me to give the game a go is below.
PS: ACG is one of the best reviewers out there in my opinion. He is has an excellent and unique rating scale.
