We all know the CI2 final boss right? and in CI3 it appeared again with the purple bolts, I also saw how there are a ton of reworks going on in CIU with new bosses. So i thought of the CI3 Boss but with a second phase, that being the Metal Egg that shoots directly at you.
I was thinking that it starts off like the normal CI3 Hen ship but when it gets to a certain point it breaks off the shell to reveal under its that metal egg and plays like the CI2 fight. obviously it would have a different wave name but it was something i was thinking about earlier.
(also spent a bit too long on the mockups)
I totally agree that this fight needs a rework, posted a topic about it not to long ago:
Obviously I am partial to my own idea, but this is actually really cool as well. Maybe not the exact same artwork as Mysterious Ship, because that could get confusing, but I like the concept a lot.
