So, earlier today, someone told me about some bugs in zombies.
One of the bugs is involves the boss of round 5, The Wither beast. Once you give it a punch, it just vanishes, he dies by only one shot.
Here’s the person that told me about it: https://i.gyazo.com/542898ebaa605393b6f5d3b53449fcc0.png
I couldn’t get any evidence, but if someone else tells me about that and I’ve seen it, then it’s real. 
Another one is related to the boss of round 14, The Ogre. It appears that in the arena “Hill House” the ogre spawns somewhere where he is trapped and cannot be killed, but here comes another problem…as you know, Zombies must be playable while being alone too, but even with 6k hp in a custom lobby, I couldn’t reach wave 14 to prove it, because the spawn rate is too insane and weapons were dealing so little damage! Like seriously, the Laser Machinegun was dealing around 8 damage to the Possessed Armor, the hex doll and the poison staff too, there were like 30 of them in round 10 -. I just simply died after all because of being afk…
So, I think that zombies needs some gameplay fixes and bug fixes, maybe buff some weapons in Hill House, if you can .
Might come with some more Zombies reports, stay tuned! 
And can someone tell me again how the png thing works on the forums, please?
