Achievement called “Conservative” in which you have to eliminate the team using only wrist blades does not count. I did this three times: the first time by dealing damage with a caster and finishing in melee with claws, and two more times fighting the entire match with only blades. Nothing.
My platform is PC - Epic Game store.
"Only wrist blades" achievement bug
I would like to report that this achievement came out when I ended the match eliminating FT only with a hook. So the achievement is awarded for using the club and its variant, and not the wrist blades, as it should be.
