Generation Zero is a co-op FPS for up to three players about humans fighting to survive against hordes of hostile robots that have overrun Earth. It was developed as a side project at Avalanche Studios, and while it wasn’t great it did well enough to justify spinning off the development team into its own standalone outfit, called Systemic Reaction, which teased its first game (under that name) back in March.

That game was revealed during today’s Inside Xbox livestream as Second Extinction, and it’s possible that you might find it a little familiar, beyond the obvious Turok ambiance: It’s a co-op FPS for up to three players about humans fighting to survive against hordes of, not robots this time, but dinosaurs. And not just the regular, everyday dinosaurs that we know and love, but mutant dinosaurs, like electric raptors and T-rexes that are even bigger than regular T-rexes. And the regular ones are pretty big to start with, let me tell you.
