Originally conceived and heavily tested as a versus campaign, version 2 constitutes a pretty big env. art pass, a significant addition of custom content, and small tweaks to the geometry for both vs. and coop. I'm interested in gameplay feedback at all levels of difficulty, specifically for coop, and will steer future updates in that direction. This is still a versus campaign at heart...if you get a chance, play it that way. For those who think vanilla versus is a bit too kind to the survivors, disable the survivor handicapping in confogl and alternatively try this approach. There's still lots to do (and perhaps a map to add), but i think this thing is ready to be called version 2.

The survivors killed the helicopter pilot that was turned into a zombie. They landed in an infected area and will have to search for a rescue vehicle. Director will show you some different ways to go through the entire levels, some of them with 3 different ways to complete them.

There are various environments on this (in development) campaign and a great variety of buildings to see. If it's the first time playing this campaign, I recommend you to restart the instructor to help you in the events. For that, type this in console: gameinstructor_reset_counts

Have fun!

Suitable for experienced players.

I had a lot of fun testing this XD This was originally a css map i made a year ago.

WWE Survival experience. Special thanks to The ElbowStealer for the custom tank music. Enjoy!

This is a quick modification of the first map i ever made about 3 years ago for css zm. It occured to me that it would work a charm if ported into left 4 dead. Its probably the easiest survival map ever, as the survivors have a perfect vantage point above the huge bunker complex which is a labyrinth

my first campaign WARNING: Only download if you like exploration based non linear maps, theres no rescue closets, dont whine

The Xenomorphs have hijacked the starship von braun and the unn rickenbacker and are using them for there own devices. Activate their self destruct sequence then kill the dragonfly xenomorph queen

Battle through the city to rescue. Me and a friend made this to teach ourselves the hammer editor. Wanted to build a short campaign that would suit short versus games (in a similar way to crash course or the passing) its playable in campaign and versus and has one survival and one scavenge. Enjoy!

The Xenomorphs have hijacked the UNN Rickenbacker and are planning to use its dual nuclear railguns against earth. Activate the self-destruct sequence by using the 7 control consoles then escape via the docking bay.

Now with VERY creepy music

This is the second of a planned 3 missions system shock 2 esque campaign.

The Xenomorphs are using the Von Brauns Simulation units to research a new generation of hunter killer hybrids. Activate the 7 self destruct control stations and escape in the emergency escape ship

This is a prototype map of the first mission of a system shock 2 inspired campaign.

The 4 Survivors have crash into a police Barricade they found out that there is a town called Greenville that is holding down the infection they must reach out this last standing place before everything goes to hell

A new breed of hunter killer hybrids are being incubated and when they hatch, your doomed.

This map is heavily inspired by the imperious system shock 2

DISTRESS CODE DELTA CHARLIE: Attention UNN Rickenbacker. This is Von Braun. Ship status critical. 80% of crew dead or worse. DON'T ATTEMPT RESCUE
