Secret ending or secret prologue(bad)

Hello again developers.I have played a bit further and got the idea for surprise players with secret ending which is not on the main storyline. That’s gonna be long so I will make it as short as possible. First, you have to find the secret database somewhere deep in the sea. There will be no mission hints nor negivation assist to activate.Just lucky find. There, the survivor will mention about the one time alian tech weapon to slay collector leviathan which is in one of the wrack at the middle of 800m big king clum leviathan. So you know what you have to do. Sneak the wrack covered in vein trap of that clum. The weapon may also be wrapped by traps so once you retrieve it, you have to swim like ∗∗∗∗ to get out of that clum before it shuts. There will also be poison leaks so you have to avoid if you don’t wish to swim without your vehicle which has 0 chance to escape.After that, kill the ∗∗∗ with ∗∗∗ killer. Than boom. Secret ending. And surprise, you have killed the only hope keeping thy virus from spreading further. The mission ends but the deserter just began. You are on your own now to kill that ∗∗∗∗ tree with the built in impossible difficulty where every fih turned into zombie and try to harm you in every way possible. No story. No mission. Just pure chaos where the situation is out of control. You can craft killer weapons at this point. Good for people who always cry to add weapon to dominate. That’s gonna be wild for them.

Won’t it be simpler to use exit vehicle crush depth kills instantly use void mechanics while searching desperately for base with only way to enter is with new prawn in some sort of monopole. Inside base is modification so player can now safely survive depth with some extinct leviathon on display
