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.
