Attention, citizens. After a couple of ooh-missus-I've-gone-weak-at-the-knees trailers, the Half-Life 2 fan-film starring Him Out Of Opposing Force has arrived. Twelve minutes of live-action Combine vs Resistance gritty warfare awaits you below. Striiiiiiiiiiiiiiiiiiderrrrrrrrrrrr!
Not too much dialogue (the right choice, I suspect), but the in-jokes and Valveverse references fly fast. Keep up now.
Well, maybe somebody's watched The Matrix a couple too many times and isn't 100% on Combine research, but that there's a good-lookin' dozen minutes.
