I'm so glad you're willing to share a story with us! And don't worry about your grammar. It seems you're language is already quite good, and we have a good team to help catch any little errors that slip through :)
I think any of the last four will fit nicely, and I don't really have a strong preference. If I had to choose I would say the Schall Pickup Tower might be interesting, because it's easy to understand, and players might find it interesting that there's a radar underneath a chest, which actually really cool :) And the Endgame Evolution also sounds epic. I'll leave it up to you though.
If you want finished writing the paragraph or two you can paste it here, or send it to me on Discord (stringweasel 0691), I don't really mind which. And it would be great of you could add a short video clip of it in effect, but if that would take too much time I could always try to do that myself.
