assuming your pc you have to left click 3 times then press f with chainsword
if you go tot combo controls in pause menu look for the heavy stun
after than go to execute them and spam shoot to over power in melee
This works fine. Also depends on the Nobs. You have regular easy to kill Nobs and I guess the others with more armor and lot more power are 'Ard Boyz, and they're a pain to take down. When you see them coming just spam with grenades and then use Fury if you have it. Fury + Thunder Hammer = none shall survive.
I mean I thoght all you had to do to take down a Nob was to press the F key to stun and then press the E key to execute. But I must be doing something wrong since it doesn't seem to work for me when I do that. Please any help or feedback would be greatly appreciated. Thank you in advance.
You have to melee 2 or 3 times and then use the stun strike to stun Nobz or anything tougher than a normal ork.
You can always use Fury as well which will make it far more easier to do it.
