It’s been years since the scattered forces of the Marine Frontiersmen last clashed with the alien threat known collectively as the Kharaa, but recently-received distress calls indicate they have returned to the galaxy in force. Want to be one of the first marines to take them on?

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.

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.

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.

New features include dynamically changing environments, a new resource model, flexible game scripting and modes, and new weapons, abilities and upgrades.

Features:

• Superior Firepower vs. Alien Evolution – While Marines form squads and use a high-tech arsenal of guns and gadgets to blast through foes and destroy alien hives, the adaptable Kharaa can evolve into five deadly forms with completely unique abilities: wall-running Skulk, pudgy Gorge, flying Lerk, teleporting Fade or giant, door-smashing Onos.
• Real-Time Strategy - Commanders direct the action from overhead, building structures, collecting resources and researching essential upgrades as the rest of the team goes toe-to-toe with the alien forces.
• Dynamic Environments – Spreading alien infestation deforms hallways, destroyed power nodes result in tech-neutralizing outages and maps continually evolve as players destroy, seal off and break open pathways.
• 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.
