This is a really bad campaign. On chapter 1, you randomly get teleported if you stand outside the saferoom, specials spawn and you and your team will most likely die. And if you reach the part where you kill the two tanks, when you step into the dev texture on the wall to get teleported, the bots won't and they'll be stuck forcing you to restart and push them in next time. On chapter two, the bots die instantly for some reason when I spawned, and the chapter was really buggy, the train moves a tiny bit, stops, and explosion happens outside and if you're too close, you die. And if you step outside, you get set on fire and die! However, it works fine if you load chapter 2 from the menu, so obviously, this wasn't tested. And chapter 3 is just fine, just a bit of an optimization issue, getting 60 ping, but it didn't affect gameplay that much. But that's about it, I would not recommend playing this.
