A scientist and her group find a new element on archaeological excavations at an earth like planet making the group obsessed and killing each other but she pulls against her hallucinations and her group in order to get the element aboard the scientific base.

Thanks for the kind works! I will change it as soon as possible. Due to my mathematics studies I have little time to write but anyway, this community is great! Cheers.

Could be good for the character to have a trait ? reckless/career-pursuing/enthusiastic scientist .. it will help you to give us a clue about hero's journey. Also the goal of main character is only to get the element on the base ? probably to be studied ? but how it will outcome ? what's at stakes? Her career/curiosity/wiping whole planet?

A career-pursuing archaeologist find a new element causing hallucinations at an earth-like planet which causes everyone obsessed murderers, but she resists and bring it aboard the base only to ? face extinction/death/something ...

This is a good idea, very high concept. I've also noticed that you have revised it since this post too and I like the revision as well. Well done.
