Go to the 'Config' Folder located inside the 'TurokGame' folder and locate the following .ini files like eg:

TurokWeapKnife
TurokWeapHandGun
TurokWeapRailgun , TurokWeapShotgun , TurokWeapSMG , TurokWeapSniperRifle , TurokWeapChainGunTurret etc etc.

and locate the following line which starts with:

;;; damage
;
;primary
InstantHitDamage=45
;secondary
InstantHitDamage=5 depending on the weapon file.

And then change ALL the values to something big like 999. eg:

;primary
InstantHitDamage=999
;secondary
InstantHitDamage=999

So, this will kill all the enemies with 1 shot. For the BOW and the StickyGun just search for the word 'Damage' under the ' ;;; Non-multiplayer' headings in the file.

Always make a backup before editing game files.
