I'd like you guy's to check out this video, Imperishable Shadows.
This was made by one of my Deviant Art Friends, A0001521, and it took him like 1 month to finish. I personally found it to be among one of the best SFM videos I've ever seen, and not just because I'm one of his supporters, but because of how awesome it was in general.
Its an SFM-made TF2 video that's mostly about a huge attack by two of the TF2 Halloween bosses (Horsemann and Monoculous), and a squadron of the Mann vs Machine robots too. It has some impressive visuals, and a few good slo-mo effects, and some other unexpected occurrences too. It was mostly done as a big Halloween special.
Here's a link to A0001521's Deviant Art profile too, where he also had posted some screenshots of this video while it was still in development.
So I'd like it if you guys watch this and give him some appreciation or something. He's one of my good friends on DA (like Jamey is), and he put a lot of effort into making this, and I don't want his hard work to go unnoticed.
