Whether you play as one of the elite marine Frontiersmen or the vicious alien Kharaa, you must use unique strategies and your abilities to win. Marines buy weaponry and form persistent squads to find and destroy alien hives. Aliens can choose a wall-running Skulk, pudgy Gorge, flying Lerk, murderous Fade or gigantic Onos that can devour enemies whole.

Real-time Strategy
New strategy gameplay allows players to Command from overhead. Build structures anywhere, collect resources and research upgrades. The marines can build phase gates, sentry turrets and siege cannons to assault the enemy. Aliens can build upgrade chambers, evolve special abilities, lay eggs and plant traps.

Dynamic Environments
Levels change as you play. Spreading alien infestation deforms hallways and causes space station power failure, halting all lifts. Destroying a catwalk's supports causes it to fall, revealing a new route. Use a flamethrower to clear infestation, spin webs to block a passage or weld a bulkhead shut for a last defense. Every game is different.

Unlimited Variations
Flexible game rules and scripting allow you to create your own unique scenarios like "Colonist Rescue", "Alien vs. Alien" or anything else you can dream up. Free automatic updates keep the game fresh by adding new levels and abilities.

A Gorge made in GorgeCraft

I am so excited to be announce the official release of GorgeCraft. It is 2 years today since the very first prototype build was released on here, and it has been a wonderful experience developing the mod. There have been many changes of direction and some inspiring mistakes, which have made the journey so thoroughly fascinating and enjoyable.

To get the mod, you need to own Natural Selection 2. Once you have that, you can download the files automatically by subscribing to the mod at the steam workshop here.

There is a basic GorgeCraft Guide on the steam workshop as well for new players. It does assume you have some knowledge of playing Natural Selection 2, and how to use the gorge to build things.

Have fun playing GorgeCraft, and remember to submit any of your artistic creations for sharing to the world.

Kinda like Tremulous, only extremely up scaled graphically (and not free) You get more than you pay for. Game-play looks solid, and incredibly balanced. And at a modest price.

No, Tremulous is kinda like Natural Selection.

NS1 came out before Tremulous, based off a Quake 2 mod called Gloom.

I think if you can run Crysis at high settings you can run just about anything, so this statement is ********. I do have a strong lineup, but my PC is not out of the ordinary and NS 2 runs just fine. (Arma II runs much worse on it)

Which is actually the reason why I came here today. I pre-ordered the game so many years ago, basically after NS for Goldsource was no longer played. I had mixed feelings inbetween and thought you were screwing up with your own engine. It ran pretty choppy at times.

Now I played the latest Beta and I'm so damn impressed, I have to appologize humbly. What you have achieved here is incredible. The engine and things possible with it are quite amazing. I would have never believed this team is only a few people in size. You've done a great job and I can hardly wait for the stuff I get for pre-ordering. I guess the artbook alone will be an interesting feat. I'd like to know how development looked like at different times!

Very well done! Congratulations on the imminent release!

He meant his system can run Crysis but can't run this game with a playable framerate. Most likely, there is a physical issue with his PC or a driver issue he is having. Regardless, don't let him stop you from buying this amazing game.

Yes, which is why Natural Selection 2 is the only game with this problem. I can run BF3 @ 2560 x 1440, with over 100FPS, maxed out, AND 2xAA. Granted, BF3 is made by a huge team, with lots of money, but still.
