The guys over at Unknown Worlds Entertainment, creators of my favorite half-life modification, Natural Selection, recently announced their plans to have NS hit the Source scene. The mere thought of seeing aliens and marines battle it out in the spectacular Source engine, with the awesome physics and graphics, summons salivation.

For those unaware, Natural Selection was the first RTS/FPS combo, featuring a single marine player, known as the commander, who played the game from a top-down, RTS-esque fashion. The game featured some great level design, but the corridors and server rooms found themselves littered with alien sludge and debris, manually built into the world.

However, the developers of Natural Selection 2 are working to remove the static alien clutter, replacing it with procedurally generated sludge which spawns itself nearby alien structures. Check out the video, along with perpetual updates on the Natural Selection 2 developer blog, where the game’s features will be detailed and up for suggestions as they're implemented.
