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.

My issue, the lag, it runs horribly even with my decent computer and adsl 2+ internet. Combine that with the standard alien in the game moves ridicolously fast, you don't even have a chance to aim at them and your already dead. Even people who are into pvp will have trouble liking this. I'll wait till Aliens Colonial marines comes out to get me satisfy my alien squashing needs.

Having no lag issues at all playing with a 460 GTX, an i5 2,66 Ghz quad and 4 gigs of RAM. Since my rig is average if anything I'd say it's not a matter of raw power that causes your problems. Maybe you want to try and tinker with the graphic settings, it may be just one or two settings that are off.

There is a possibility to purchase the cd-key deluxe edition DLC for the basic version of NS2? I have a normal version and I would like to have access to exclusive soundtrack and artbook.

Interesting but not important. Few Arabs would play NS2 and most people just call the team "aliens".

I finally realised that I was willing to buy this for the price it's at. And as it sits, installing right now, I am unexpectedly pleased with the mere 2.1 GB Steam is reporting I will have to download.
If Steam is correct, you've packed a lot of awesome into a quarter of the download size I had been expecting.
