Nightfall seemed pretty tough this week. I had a go at it with two groups, one of which was trying to exploit a cheese on it, with one guy staying behind to gain lists of time, and the other two going on. Didn't seem to help, much better run when I did it wholly legit and we just had three people shooting always.
Top tip tip for the walker, drive past it, go in the tunnel and kill it from there.Much easier than doing it from the side you encounter it on
