eh?
zombie mode is REAL harder than spider mode, because if ur not defending and he uses zombie fury theres no way to defend from it anymore, and when he turns on spider mode you can just spam attacks and he will keep dodging them and being hit instead of attacking you, when i killed his zombie form i had like 30% of my health, but with this "spider bug" i easily killed him, he could just hit me with the vomit and sometimes with the fireball, the lazer is easy to defend, because he always uses it on same place.
