Tips on animation

Hello everyone !
First of all, i am not animator and i don’t have time to animate 3d characters.I am currently making a melee first person fight game , similar to chivalry.Therefore i have a problem.I got a bunch of animations from mixamo but i don’t know if these will suit in a first person game , as with most of the animations ,the player won’t be able to see the weapon he is using.This leads to my second question : is it possible to find melee animations or even to get the one’s from chivalry medieval warfare to use in my game. Any tips or comments are appreciated and give me your opinion on character animations used for first person animations.
Thanks in advance :wink:
