I understand your head ache.
Heres my take on it:
Special sense: Detect hostility 10Pts
360 degrees 5pts
And
2d6 Aid To Power framework and powers with in(+1/2)
AutoFire 5(+1/2) Autofire based off Per roll (-1/2)
+48 to Max(24) 54points
When the Pc encounters negative emotions you may ask for a perception roll for every 2 points it is made by, thats 2d6 to the pcs pool, to a max of 10d6 (possibly 60 active points)
Hostility can be considered any negative disad(Casual killer,belligerent,hatred of whatever(if its active) or a hunted(again, if its active))
