Narukami solo Mashmak (extreme) players are absolute psychos, I must say. Not sure if they were teaming or only calling a truce because they were both Narukamis or what, but maybe also simply couldn't get the kill on each other because they're both perched on opposite ends and only shoot at visible targets.
From the start of point A opening up to the closing final moments of B, I had to deal with two Narukamis on full guard dog mode until someone lost their patience. They had close to zero aggression in chasing me down so I could always recover (I'm Alysnes), but would lock down the extract. All 3 of us practically sat still for upwards of 5 minutes and the silence was only broken from an Inferno bot coming in and shaking things up, to which eventually drove them to move as they got greedy to loot and compromise their bunkering which allowed me to eventually kill them.
I think the main thing that made them psychos to me is the loot on them was pretty bad (like blue gear and below).
I guess that's just how it is when you play Narukami in solo.
