theres a reason why putting it in flash was bad.
when converting normal video files into Flash Video Format, it greatly degrades the quality. This would be a lot better in its original .AVI or .MPG4 or whatever format it was in before you converted it to Flash.
I wouldn't consider this a "Flash" video and I would say this belongs on youtube or some other video website. If you were to make a soundboard or a music-maker where you can place the sounds on a timeline that play over an elapsed time, that would be more suitable for Flash format.
Then again, the makers of this website are nimrods that will place anything, regardless of its relation to the bareroots of the site, that display recent nerd culture on the frontpage. I don't see how this has any relation to half life other than the fact that the game itself is made using the same game engine... Newgrounds needs a new TF2 collections page.
the two came from the sound, and the sound only.
