Remember that HL1 snowball fighting mod back in the day? It was around for one of those winter season. I always thought someone would bring it back for HL2 and I'd get to re-live that fun mods game play all over again. No one did tho, and Ill be damned if I let that happen again this year! Here's a snowball fighting mod for release this winter!
One thing I'd suggest is adding a sound effect that plays when a player hits another with a snowball using sounds from Half-Life 2 such as any of the male cheer voice lines or laughing, maybe even use a couple of Barney's lines.
I like that idea, I'll keep that in priority for the next update.
