Natural Selection 2 Trailer

Sequel to classic Half-Life mod launches on Steam later this year
Unknown Worlds has released a teaser video for Natural Selection 2, a standalone online FPS that pits aliens against humans in a strategic and action-packed struggle for survival. Two teams of up to 16 players face off with unique abilities in dynamic, evolving environments that change as you play. You will watch spreading alien infestation deform hallways, and then use a flamethrower to clear it. You can cut the power to disable marine structures or weld a loading door shut for defense.
