I know I have not been doing party cheats, but I am now! Here are cheats for chapter 4!
First, when you login, click the files.
Now, if you do not have all the items, get all of them!
Ok, go to Herbert’s HQ and go through all the rooms until you get stuck.
And now, put on the item that you need on your penguin and now you now are past.
And last you click the computer and play the game.
Hope this helps. Bye.
