'One 4 Nine' is a five-level campaign for Valve Software's Left 4 Dead 1 and 2.

Supported game modes: single player, co-op, versus and survival.

The setting is the Nevada Desert. The U.S. Army have built a Military base around an ancient 'alien tomb', and after years of trying have finally managed to open it.

The four survivors - Francis, Bill, Zoey and Louis - have heard rumors of a fortified safe zone located in the U.S Army's base, but have no knowledge of the tomb, nor what will await them upon arrival...

One 4 Nine is featured by Valve on l4d.com from today for the next few weeks. Many thanks to Valve for featuring my campaign.

I've got no plans at this time to update either the L4D1 or L4D2 version. Both versions were released about two months ago and my "list of things to fix" is precisely zero for both, not even anything minor. So, the current versions seem pretty solid and stable. Unless any reports of major bugs are reported I'm regarding L4D1 v7 and L4D2 v5 as my final releases.

Since there may well be an influx of new people to One 4 Nine and want some more info, here's the website for the campaign One4nine.co.uk

Anyone who doesn't understand the finale or who just wants the official explanation can find it here One4nine.co.uk [CAUTION: major spoilers, do not read until you've played through the campaign]

Thank you to all who have taken the time to download and play One 4 Nine, and especially to email me providing feedback. I hope you've enjoyed it.

For the last two months I've been working on my next campaign. I'm not releasing many details at this point, just to say that it's not a sequel to One 4 Nine, it uses some Google maps of a location in Northern England as a starting point, and is going to be called "The Bloody Moors"...

I'm nearing completion of the L4D1 version of the campaign (I'll convert it to L4D2 when I'm happy with the L4D1 version).

Just played it and it's awesome. I love the lighting.
Only problem is I kept dying at the finale and had to redo the whole level, it definitely got frustrating.
Other than that it is a great campaign.

Thanks. :D I've already split map 4 into two pieces (map 5 starts just prior to entering the tomb) and I'm currently adding a new section to map 4 (since it's now a bit too small).

Hey, I wrote a review for your campaign. Some feedback in it, which appears to be echoed by some other commenters here, but overall you've got an excellent campaign here. Nice work.

Many thanks for the review on your website. :D

btw, there is a gun to pickup in the basement of the residence before going down the big lift (probably where Zoey found her weapon), and there's also an armoury at the start of map 2 (the door sets off an alarm when opened and alerts the horde!) :)

Downloaded earlier today this campaign from l4dmaps and i can say one thing: it made me reinstall L4D after quite some time and it was totally worth it. Excellent work on everything. Loved the design, loved the yellowish tint, loved the totally unexpected finale, congrats!

Just some words for the finale. Except that i found it a bit long...

[spoiler_mode 1]
...i was expecting something more out-of-the-ordinary for the rescue, anything than just a fade-out. Maybe a portal to open through the tomb, for example...
[spoiler_mode 0]

So my only suggestions are: a more special rescue and maybe split the finale or cut it a bit.

Anyway, excellent work again. Keep it up............

Thanks for your feedback. A couple of people have now mentioned splitting map 4 into two pieces. Perhaps I'll do that for v2.
