Well this can still go hand in hand with DayZ and your new gamemode, this is a gamemode about a giant group that decided to escape earth away from that apocalypse by taking a ship to some other planet (Why not Mars? or Moon? or some new planet or galaxy, possibly able to go to other planets and stuff?) Its about a war between aliens and humans or a civil war with 3 factions of human (and still maybe some aliens) that upon joining you are randomly placed in 1 (you have 1 redo or you can buy 1.) you can go to other planets by going to a Planetary Station (or Star Station or Space Station whatever) where you can go into shuttles and click a button to be tped to a "planet" and maybe for different sized planets you can have the layer tped to the other side of the "planet" when you hit the edge (you "pushes" us back at the edge of the map on your other servers or have it like the random warp on infernal hit the side and it tps you to other side of map.) I know your buzy with DayZ update and your new gamemode but this is just a idea.
