Natural Selection is an action-strategy game for the PC. It is a "Half-life modification", which means it is written on top of the Half-life game engine. "Mods" are a new sort of underground game development that enables small teams to create games using the technology of existing games. This means less expensive and lower risk game development, which allows experimentation and innovation. This arrangement also implies that "mods" are made as art, not for making money. When complete, Natural Selection will be released for free to all owners of Half-life, which is required to play Natural Selection.

Game summary

Multiplayer-only Half-life mod where one team plays marines and the other plays aliens. The humans must keep their cool and work together to assault an alien-infested spacecraft or colony. Marines vs. marines and aliens vs. aliens scenarios are also supported.

"First-person strategy" with a real resource model and consequences for actions. Both sides are genuinely different and together they accommodate different play styles:

Marines::Fighting skill is less important, strategy and communication take its place. Playing as a marine will be a tense experience with methodical planning and strategy, interrupted with action.

Aliens::Playing as an alien will be an intense action experience, rewarding reflexes and alien heroics. Communication and coordination don't require typing.

Accessible, fast, mouse-driven interface: no keys beyond those used in Half-life needed.

Simple to learn and play, it is hard-core action/strategy for a mainstream audience.

Innovative social dynamics lead to memorable games.

Atmospheric indoor sci-fi environments full of steam, smoke and ambient soundscapes

Natural Selection is out, go get it already! :P

Natural Selection Source Code Released!

Posted by Hugh
Original news post available here: Unknownworlds.com
                    Natural Selection Source Code                   

Back in 2002, Natural Selection was released…

Since then, lots has happened. Unknown Worlds was formed and NS2 was released, reaching multiple times the number of players the original mod did. Charlie, the creator of NS, has come so far that he’s now working on a new game: Subnautica.

But we will never forget what started it all. Today, we are proud to announce that Natural Selection Source Code is now available to anyone, free of charge. Head on over to GitHub to get it. It’s not ‘open source’ – There is some legal hoo-ha that prevents that. But it is all there.

Natural Selection 1

Got balance?

You can use the NS source code to make your own version of the original game, fix problems with it, make new problems, or just see how the game worked.

We hope you enjoy tinkering with it. NS was one of the greatest mods of all time – And we can’t wait to see what you are able to do with it.

I saw this mod appear on here a few days ago and it seems to be well taken by the users!
I do have some more info on this mod, if you want to take a look at Readyroom.org there is a ton of news, shots and videos there for you to take a gander at. That site is run by the crazy MonsE (the man who posted this mod on the DB here).
And just a shout out to the guys making it, I know this has been said before, but damn nice work guys!

These are stories from the playtesters, which give you a good idea of how the gameplay will be. Some amazingly scary, funny, and just downright awesome stuff in here.

I think this new game Battlefield 1942 may take over the internet when it gets released.

2 other mods that will pwn are Starship Troopers, the english version, if it ever gets going again, love that mod.

and Operation Red Falcon, it looks so so sweeeet. I just love it, check them both out on moddb

I am so excited about the upcoming release of this mod. I am mapping for natural selection, so I am even more anxious to see my map in action on servers (if I can find a custom maps server). I just hope it's ready in time for July 28th's LAN party...
