Okay. So. Here's what I recall from the stream - pardon the mess.
ZOMBIES CAN NO LONGER GO PAST THE WALL IN ZOMBURBIA. THE SPAWNCAMPING HAS ENDED.
MB, Zoologist, and Chemist are getting nerfed. Warp is seeing some changes.
Sharkbite is getting nerfed and we can now cancel the barrel. Cpt Cannon is getting buffed?
Sunflower's getting a lot of damage buffs across the board. Dark Flower is getting a CD buff.
Rose is getting slight buffs to her homing/fire rate. They also removed/reduced the movespeed reduction for charged variants
Citron is getting buffs to damage, overheat? Crit area is now his face. Electro and Ice variants will see a buff.
Super Brainz is losing a lot of things with Turbo Twister. Electro Brainz is getting nerfed.
Chomper is getting camera fixes for himself and burrow, digestion upgrade has been buffed, Chomp thing is able to regen at all times - hinted that other variants are getting buffed.
Corn is getting buffs, BBQ is not. They will be more accurate.
Electro Pea is getting buffed. Heard nothing about Commando Pea though. :/
Party Characters are seeing a buff. Unlock them now, they say....
The stranger ones are buffs for the imps z mechs. But that might be negligible since his counters (Citron/Rose) are getting buffed. Imp is getting a more forgivable hitbox.
...and Jade Cactus getting a random ammo/damage nerf. WTF?
