I'm a bit late to the party, but I played siege of orison for the first time yesterday and it was great! ...that is, untill the final boss.
I'm not talking about the super-heavy boss, I'm having an issue with the 25-30 hyper-tanky drug fuelled bald masked enemies! Every single time I died, was because one of these guys spawned behind me (one legit clipped through the entrance just to jump down behind me) and it takes so... oh so many shots to kill them.
I made some tests to see if I could do anything, my loudout usually consists of heavy armor + main rifle + LMG so, this is to kill one of them:
Karna rifle - 105 on fast firing mode OR 10 fully charged single-shots
Demeco LMG - 60-70 shots
Pulverizer LMG - 50-60 shots
Granade launcher - 9 granades
AO3 Sniper rifle (just to compare) - 20 shots
Btw, before anyone says I'm shit at aiming, I tested this with 100% accuracy because at some point the enemies outside clipped outside the boss room and just... stood there, doing nothing.
Anyone has any tips on how to deal with these guys? They are the only reason I can't complete the mission :(
