Well, having pretty much exhausted the origoinal Door Kickers, I also took the plunge after watching far too many Combined Pairs Gaming reviews on Youtube.
Loving the complete vibe change from very restricted SWAT ops (in terms of lethality) to glorious explosion's, wall demolition, etc. of #2. WOW!
And they've just released a Suppression mechanic, which means that SAW gunner is now very useful..
I won't mention that I've named my crew Jason, Ray, Sonny and Clay (Marksman) (with Davis for a laugh), whilst binge watching a certain TV series - it really adds a solid persona to my operators.... On CQB missions, Clay rocks a Shottie (which has also just been released)
