Alright first from what i have seen

1.PCX will now get 50 stamina

2.jeff the killer ( i dont know the full name ) is coming in the next update or another

3. There is a new item called Flashbang that is a human item and when you use it on a monster you will make him see nothing for a short time making you be able to escape some chases

4.There are 2 new maps coming to pillar chase 2

Those is

My World ( PCX Map and green hill ) And

Goobled Up ( i think its the name ) ( WYST Map aka pac man map that you need to pick up 150 PELLETS AS THE FIRST OBJECTIVE )

5. Rosemary will have 43 stamina now ( i dont know if it was already like that but yeah )

6. The pillars is getting a rework on the map and now there will be a entrance to another floor with a platform that flings you up but doesnt stun you

Also clean vents objective instead of being 4 vents ti be cleaned, now it will be 6 to be cleaned and some buttons changed position

Thats pretty much everything i have seen on the public test
