Natural Selection was one of those cult games that never really got the publicity it deserved. Probably because it's merely a glorified free mod for the popular PC game, Half-Life. Since the Dtoid team doesn't give this series much notice, I thought I would do it for them. Albeit, I will give credit where credit is due.
Pitting Marines vs Aliens (or Frontiersmen vs Kharra), NS was able to successfully combine elements of a first person shooter (FPS) and a real time strategy game (RTS). So imagine playing a futuristic Age of Empires where you directly control just one of the ground units and take vague directions from your commander (if you're a Frontiersmen) or run around aimlessly on the walls and ceiling as a Skulk until you find a juicy marine to eat. Or, you always have the ability to evolve into a bigger alien entity. Perhaps the unstoppable Onos, by chance?
Being a Half-Life mod, NS naturally drew in a select group of PC gamers, and to be honest, playing online nowadays is a fairly difficult task for newcomers. "What's an Armory look look? Oh, you want me to BUILD that? What button do I press? OMFG THE SKULKS THEY CAME AND WE DIED!" But generally, people are understanding and will show you the ropes. We were all n00bs once, and most players remember how daunting it can be entering a server for the first time and having less than nothing of an idea of what's going on.
While there are still plenty of thriving servers, most of us NS players are patiently awaiting the release of Unknown World's newest project, Natural Selection 2. The sequel has been crafted from the ground up, with it's own custom engine, real time lighting, and dynamic infestation technologies. You can pre-order this beast for a mere $19.95, or show your appreciation and get the Special Edition for $39.95. Oh, and don't forget to watch the trailer I've posted below.
