I've played a dozen or so survivors games and this one manages to have a particular sort of grip on me. Unfortunately, it is difficult to put into words why I likely won't be able to quit thinking about it until I've unlocked everything, but the gameplay is just a bit more involved that most of the other survivors games. I've yet to get to the point where I'm so OP by my leveled up weaponry that I can fall asleep and still complete the mission (as is the case with just about every other survivors game.)
