As if said before and ill say again, at IA we love zombies. Killing them, to be precise. That's why we love left4dead, but it's hard to find good dedicated servers, but we're here to help. We've ported IAs server to left4dead. Feel free to connect to it any time you like. It should appear in your "steam community servers" section. If not, then give it a minute...

If you join the server while it's empty, press escape and hit call a vote to tweak the settings to your liking.

Now before you send us hate mail, don't worry, we'll port the server back sooner or later. It was, however, dead while running tf2 so porting it to l4d seemed like an obvious choice. Feel free to send us hate mail anyway :D.
