True fact: natural selection, the “survival of the fittest” cornerstone of Charles Darwin’s theory of evolution, was named after Unknown Worlds’ Natural Selection 2. Yes, that’s right: Natural Selection 2 has been in development since the mid-1800s. Check a history book. It’s the truth.

But now, after generations of tweaking and perfecting its particular brand of asymmetrical aliens vs marines blasting/teeth-gnashing, the developer’s ready to unleash its promising creation on our lowly, non-immortal forms. What exactly will you get, though? Let’s find out.

Natural Selection 2?s dropping on a thus-far-unspecified day in October, but pre-ordering – usually a dirty word that I won’t allow to escape from my mouth in even the most hardened and gang-violence-prone of nurseries – is actually pretty tantalizing here. Basically, the standard edition will run you $24.99, but if you snag it before launch, you get a free upgrade to the $39.99 deluxe edition – which comes with a soundtrack, art book, special armor, and other goodies.

Granted, previous supporters of NS2 are the real winners here. To show its gratitude, Unknown Worlds is handing out the deluxe edition, a free additional copy, and continued beta access for folks who got in on the testing process’ ground floor. That’s pretty cool, I think.

But is it worth risking your time, money, and pristine, un-trampled-by-giant-elephant-monsters body? Well, you can watch an entire shout-casted match below and judge for yourself.
