Southernmost Combine is an alternate epilogue to Half Life 2 Episode 2, in which Gordon Freeman is sent back in time to the 1980´s to stop a Combine recon deployment happening in the southernmost land of the world. There are a few deviations in gameplay mechanics (more tactical and slow paced, no gravity gun, inventory) but it´s still Gordon fighting the combine and rebels helping him to achieve it. This is a small episode consisting of a variated set of scenaries with unique art made ex-profeso to bring Source to the look of the southamerican region in the 1980´s.
Good pipes, I'd add some decals or dirt though.
Haha i beat you on that. Decals of leaking water were alraedy added :D
okay then, how about some thick roots growing through the concrete? just put the bottom of a tree model in such a way that the truck and branches seem to protrude through the concrete, then place an upside-down displacement on the ceiling covered in a dirt texture. one of the shrub models would work well too.
Eh... Wrong picture? this is an underground corridor inside a powerplant, everything 30 meters away in all cardinal directions is concrete, pipes and steam generators. There´s no way a tree can grow there. The upside down displacement could work though as some kind of dirty.
