I’ve got a game where I started in a lab with (normal spawn IIRC so no idea how) 30 mini nukes. I also found a lab with a teleporter/portal… so plan is, get suped up, install storage CMB, put in mini nuke, then “go back in time” Terminator style in a regen game, and nuke the “first” lab that caused all the trouble… ending the invasion. 
But as I’ve posted many times over. The option to go through a portal/rip into the triffid+fungal+slime universe/planet as an end game infinite wave enemy spawn ending is IMO a fitting end to the max stat character. (A message would open up when interacting with a rip, on entering would spawn a dungeon/map where it’s nothing but monsters coming in for you!)
