How to get all bios on Completing The Mission. I was able to get all bios in ~3 hours using this method, and was able to get it even faster on my second try.

I'm assuming if you are here you already have basic knowledge of the game. If anything in this guide is confusing, you should play through the game first, and just enjoy it.

As for the guide, the first step is just going through all of the fails on the level, and just right-click as many people as you can. It's ok if you missed a couple, just keep going. This should only take a couple hours on Completing The Mission, absolute tops.

After going through the game frantically right-clicking, the odds are that you didn't get all the bios. so now you need to go to this site:

https://henrystickmin.fandom.com/wiki/Bios
(This is the Henry Stickmin fandom)

Scroll to the level you are getting the bios on. If you need a bio, you need to find it on the site. The names of the bios are in order as they are in the bio menu in the game. For example, Jacob Rose is the fifth bio is Stealing the diamond. He is also the fifth on the list.

Now, to find how to get the person in question's bio, you click on the name in the website. It should give info about that character, including their appearances in the game, and what scenes you can find them in. It may sound like a handful, but you'll get the hang of it eventually.

Here is my method for achieving all of the bios, and I hope it helped someone. Good luck! If this helped please like os others can see and just maaaaybe an award if you feel so inclined.
Adios
