Any tips for surviving the late game?
The fallen empire that borders my empire woke up and became Jingoistic Reclaimers, so they're pretty hellbent on retaking the galaxy. Unfortunately at almost exactly the same time the Unbidden arrived on the other side of the galaxy. I would have liked to have dealt with the Unbidden ASAP but the Jingoist Reclaimers declared war on a member of my federation. They had a fleet strength of 140k which put to shame my 40k fleet pretty easily. Thankfully he mostly wanted the planets belonging to my ally (though he did take my shiny new gaia world

). After the war was over I abandoned my federation to strike out on my own because I figured I'd be better off without them.
I was licking my wounds and rebuilding my fleet when another fallen empire woke up beside me. This one was of the guardians of knowledge (or whatever they are called) variety. I thought they'd be pretty mad at me because of my synths and other various dangerous techs but they sent me a message that was something along the lines of the galaxy is ending lets be best buds. So I formed a federation with my new Watchful Regulator friends.
At this point I'm pretty sure I've lost though, my new awakened fallen empire friends are decently strong but not as strong as the big angry reclaimers on the other side of my empire. And the Unbidden have been expanding unchecked for a while now, I have a feeling it is too late to stop them, last time I sent a fleet over it got instantly devoured by a multitude of large unbidden fleets. You don't seem to be considered at war when fighting the unbidden so I can't really get my Fallen Empire buds to go on a field trip across the galaxy with me as far as I can tell. Not that the follow my fleet thing always works anyway, seems pretty hit or miss if they follow you or not. I still can't seem to figure out how to control Federation fleets when I'm el presidente either, they seem to go where they please.
I'm curious to see what happens in the long term, I'm assuming the unbidden will devour everything including the reclaimers. In the meantime I'd like to see if I can find any remaining space boss monsters, I've killed two so far. I haven't seen the dragon yet though.
