I say it seems similar to the walking dead cause it's another survival type show against aliens instead of zombies.
Taken from Tv.com
"Written and produced by Robert Rodat and Steven Spielberg, this show takes place after an alien race has wiped out the majority of the human population. A group of soldiers ban together to try to stand up against the alien force."
It'll air in June and here is a trailer:
