no FPs or Scrakes so the Kat is perfect for use there. like the container wave in KFO Frightyard. If I am being serious as a zerk I use the alt-fire on the Claymore, I fnd the Kat can be fun but pointless beyond that, I normally just go from axe to claymore and not waste my money on the Kat upgrade. so a commando opening up on a scrake will have no effect beyond dealing damage. When you have a scrake stunned he won't un-stun from fire unless he is hit with something that should stun him and misses. You can not un-stun a scrake being flinch-locked since he is not stunned to begin with.
for Zerk there is the 'flinch-lock' and 'stun'.
