So on my last few FSC runs I've found myself rushing the middle section of the map right after the 6 statue room. Rather than the usual thing of blow up boxes, grab totem, kill zombies, blow up more boxes, hit buttons, etc..., I'll instead just rush past the spikes, kill the two wheel launchers with my polaris, and then rush past the next shadow fire bramble and kill that wall of wheel launchers while the rest of my team cleans up behind me.
I think soloing I'd still do it the slow way, clearing it sequentially, just to satisfy the the "no crown left behind" OCD gremlin in me... But I dunno, when I've got a team mopping up the slags behind me, why not?
I'm almost tempted to rush the 6 statue room too, but I'm not sure my team would appreciate the two wheel launchers spawning early...
So much faster than any pulsar shot :P
