Natural Selection 2 closed beta announced

The Natural Selection 2 closed beta is now ongoing announced developer Unknown Worlds Entertainment for the PC first-person shooter realtime strategy title that has been long in the works since at least 2007.
Here are the features you can expect to experience in the closed beta.
TWO UNIQUE SIDES
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 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 smash through doors.
REAL-TIME STRATEGY
Commanders play from overhead to lead their team to victory. Build structures anywhere, collect resources and research upgrades. Marines buy weapons at an Armory or build sentry turrets and siege cannons to assault the enemy. Aliens build upgrade chambers, evolve special abilities and plant traps.
DYNAMIC ENVIRONMENTS
Spreading alien infestation deforms hallways and causes space station power failure, turning off lights and shutting down marine powered structures. Use a flamethrower to clear infestation or weld a bulkhead shut for a last defense. Every game is different.
UNLIMITED VARIATIONS
WYSIWYG graphical tools and powerful scripting allow you to create new weapons, scenarios or entirely new games. You’ll get all our tools and Lua source code we’re using to build NS2. Ongoing automatic updates keep the game fresh by adding new maps, weapons and abilities.
And here is a new trailer for the game.
Here is some gameplay footage of the Alpha version.
