interesting battles

so there i was doing some mission (the one where you have to turn on the sentry guns down the road) and I come across the biggest swarm of hellbugs I have ever seen. after chucking pyro grenades over and over into the swarm (instant refill every multi-kill) I find a hulker. suddenly, a monarch shows up and fights with the hulker. I learned something from that fight... Hulker can 1 shot a perfectly healthy monarch! then he went hulk smash mode and slaughtered more hellbugs.

has anyone else seen any other cool fights?

I see raiders killing hellbugs all the time. Nothing as epic as what you just described though. Got to keep my eyes open.

I learned that Dark Matter and EMC hate each other so much, they'll stop fighting me to fight each other (at least until I shoot one of them, heh.)
