Second Extinction throws a whole lot of familiar ingredients into a science fiction blender. It's got the repeatable cooperative action of Left 4 Dead, the comic book dinosaurs of Turok, and even the online world tendency shenanigans of Demon's Souls (really). You can look at any element of Second Extinction and see exactly where it's come from, but the shooter manages to build its own identity where intelligent tactical co-op shooting and gloriously dumb dinosaur gore meet.

It's the future. Earth has been overrun by evil mutant dinosaurs, and you're part of a small group of humans who have returned from space to take the planet back. In practical terms, that means you're dropping from space for brief bouts of mission-based dino murder. You drop into one of a handful of open-ended maps, follow big objective markers through hordes of violent dinosaurs, maybe complete a few side missions, and then extract to collect persistent rewards. Rinse the blood off and repeat.

Once you're on the ground, Second Extinction moves fast - and so do you. Dinosaurs can surround you in a hurry as you move toward your objectives, and your experience might go from 'lonesome stroll' to 'full-on dinosaur stampede' in the space of a few seconds.
