Accepted answer: no
I am playing the Vendettas campaign offline as Inugami. I am currently in the Old East Docks location, and I now have to fight the level bosses, Amelie Dubois and Jean-Luc Lambert, face-to-face. I am playing in Hitman difficulty, which is the default difficulty.
I have tried several times but I always get killed in the part where I have to battle them face-to-face. (I have been able to beat them earlier when I had to fight them in a long-range battle.) Occasionally, I have been able to kill Amelie Dubois, but I am unable to do significant damage to Jean-Luc Lambert, and I end up dying. Jean-Luc seems to be bulletproof and swordproof.
What's a good strategy to take care of these bosses?
When playing as Inugami, I have not been able to take advantage of my Darkness power, Swarm, as making its cooldown faster requires me to kill someone. Inugami's unique weapon, Kusanagi, also does not seem to help, as I take up loads of damage when I do a melee assault. I am also unable to quickly regenerate health, as I am not able to kill enemies with Kusanagi.
