Power nodes are a new feature in Natural Selection 2. They control the lighting for rooms and power for marine structures. Their use is a prime example of the Spark engine's dynamic lighting capabilities.

When a power node is damaged, the lights in a room are dimmed. Also, marine structures cannot receive the crucial energy they need to power their many structures. This means infantry portals cannot spawn reinforcements, armories cannot dispense ammo, etc. Marines end up literally fighting for their lives.

In order to repower their structures, the marines must weld any damaged power nodes. This can be done by commander-controlled builder bots called MAC's. Once a power node is repaired, lights in the room turn back on and structures come back to life.

This new concept increases strategy and forces both teams to fight constantly over territory, since controlling power nodes effectively means control of the room. To demonstrate this concept more clearly, NS2HD has posted a very nice video.

Is the flamethrower itself going to throw dynamic lights later on?

This is looking good. But your flame thrower and flash light dont make shadows and the guns muzzle flash doesnt create light :(
Will this be implemented later on?

Actually, technically speaking, it always had a dynamic light *option* (and by that I mean, you could have a few dynamic lights - namely light_dynamic and later env_projectedtexture; the player's flashlight also counts), which improved over time. It's still primarily lightmap based though; even AS only uses the dynamic ones where they count.

So yes, Source may be a very good engine, but it's still showing it's age and this *is* still an improvement over it.

Yeah, but Source is modular also, it's gotten alot of upgrades, have you seen Dear Esther? It's amazing, realistic foliage.

Ith's not the engine's prolem. It's Valve making sub par looking games in order to be widely playable. Modders using valve made content for their games, or not being very good at making their own. There are a few source engine mods that look great. DE is one of them.

Also there's Blade symphony, Ivan's secrets, lost hope, Tales from the Galactopticon, Sabotage (for it's particle effects), and Debauchery. Just to name a few.

Source is still a damn good engine. It just needs good artists to make it show.

These graphics are amazing!
Same thing as the first 2 comments though, I hope dynamic lighting is implemented for the flames.
I will definitely purchase this game. :D

Looks like the flame is just an on-screen sprite rather than a particle effect; and yeah, it's not casting light. Also, when the power goes out, the self-illuminating light models / textures are still fully lit, which looks a little odd.

Still, an excellent technical demonstration nonetheless!

I dunno if that's a problem for Source, the whole power node thing.
Someone made a pinball game using Hammer's I/O system mainly, so a couple of blinking lights w/ timed events isn't much of a challenge for Source.

But I do agree with Spark being a lot better choice if you're to make any profit with NH2.

Impressive work you've got your own engine! I have no idea whether Unreal3 really can't do what you show here, but I think it's also good to see that game engines CAN be powerful without a 'hype' about them ;) *ducking and running*

As it is, the power node system seems pretty annoying, as it breaks so fast.

"the turrets still work but they can't aim"
-What? so they'll just shoot at a fixed angle? As in not sweep?

BTW keep the female commander voice, I like it. MAY THE POOP BY WITH YOU!
