Check out the teaser for this.
It goes until the humans are wiped out. Zombies respawn, humans don't.
Humans will be gagged from using chat. Only communication will be voice chat, which is 3d voice chat only, and you won't see your friendlies on the map so it's a unique and terrifying environment. Humans will start dispersed and I'll be directing the zombie team. Dead humans join the axis and become a zombie.
There may be more than one human faction competing against each other as well.
I anticipate this being even better than last year since it was very impromptu last year.
Time will be announced later. Very likely during ~3PM - 7PM EST Saturday Oct 31st.
PW = horror
Check out the steamgroup for later details.
You have to have the Resistance and Liberation mod for HL2. The engine and the mod are free.
This game mode is a mod of the game, no additional download required outside of what the server gives you.
