I've killed several Zombies by sneaking up from behind, knifing, and then stomping. It's possible the knife only inflicts knockdowns. The melee attacks you can do (roundhouse kick etc) remain buggy and unusable as ever
There seems to be multiple gamestate bugs. In new mission 3 (old mission 2), when exiting the mansion again, i noticed my clothes fixed themselves.
Zombies also have what feels like I-frames. With them staggering, i've sometimes pumped five bullets in their heads, but those sparked(!) and left smoky residue on their faces instead of drawing blood. And obviously it didn't seem to kill them.
Dislike the new difficulty system. Basically you either pray for crits which still one-headshot Zombies or you make the effort to get hit every two or three Zombies so your damage output remains working. Or you get homing charged by a fattie for 90% health. Attacks on you while nude HURT.
And my personal pet peeve, that one overdramatic superlong "im hurt" animation Julia does. When it starts you can basically grab your phone and start checking your emails, because you aren't going anywhere for 30 seconds.
