Only a few dozen people have max score on rein and I didn't see any completions uploaded, so I'm publicizing the routes I found. Free top 50 to any of the 5 people who stumble upon this. 0:00 - Recruit 1:33 - Agent 3:31 - Veteran
Yeah, if I remember right I did this all on release day, before any max score solutions went up. I had a blast routing it on my own, and I'm sure it's cool for you to see what I came up with as well.
i think the spawns are somewhat random, took me a few tries to get them all. it might help to give them a few seconds in LOS to group up. also firestrike can damage from range to help kill them before they explode.
