I really like this level of gameplay. They're all experienced enough, and have enough training in common that they function like a team and communicate extremely well, but they didn't plan intensely nor demand too much from any one player. Laid back end of Mil Sim but truly effective.
I donno, but it looks like it could be possible to solo this with a suppressor. I'm guessing 150+ Nine tails NPCs. . .would be fun to try.
