...not impressed at all.
I checked the video linked in the twitter feed. I wasnt really impressed with what I saw. The art style is cute and all but I'm hoping the final infestation in NS2 is a 3D rendering like the tech sample from a few years back and not like that painted on sample from the PNH video. What they presented in that video looked more like the infestation that we see in it's current form, which I understood is only a place holder.
I imagine the final DI to be a slowly creeping 3D carpet of ooze that covers anything it touches rather then a shader effect that paints textures a different color.
(p.s. I still prefer calling it DI over croach or whatever it was changed to)
