Well this idea can either be for a new merc, or be applied to all mercs having something to cut.
When using the knife the damage is given over 1sec, depending where you aim at.
For example you could gib 2 downed players with one swipe, if they are near together.
Or you could carve a smily into a wall.
Well it sounds easy but I guess technically it’s complicated.
Basically you can dmg multiple targets with one use of the knife.
Well maybe this should be applied to swords… I don’t know. It’s just an idea I had now, while watching riding shotgun.
