Left 4 Duluth
Left 4 Duluth

One Hill of a City...

Left 4 Duluth—a local art and music showcase—offers four new chapters of mayhem set in this idyllic Northland city. Battle lifeless zombie hordes as you travel through UMD, Fitger's, the Skywalk, and Canal Park—where safety lies just across the iconic Lift Bridge...

Our mod has maxed out the limits of the Source Engine. Carmack's code can take little more ;) Please see our official website for recommended graphics settings to get the best gameplay experience!

Wyandotte Boat Club
Wyandotte Boat Club

With Scavenge Mode! My first L4D map, based off of an actual location, the Wyandotte Boat Club. The Wyandotte Boat Club is an organization located in Wyandotte, Michigan, along the Detroit River, devoted to the sport/recreation of rowing. And yes, there are zombies.

Drop Dead Gorges
Drop Dead Gorges

Originally conceived and heavily tested as a versus campaign, version 2 constitutes a pretty big art pass, a significant addition of custom content, and small tweaks to the geometry for both vs. and coop.

Though coop is encouraged and conscientiously supported, 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.

Half-Life 2: Water Hazard
Half-Life 2: Water Hazard

REQUIRES additional addon to display textures: Half-Life 2 Texture Pack (linked below)
Chapter 4 & 5.

This campaign is very long and rather difficult! Be Warned!

Also includes the "Black Mesa East" chapter but compared to the rest of the campaign it's a rather short portion. Despite it's name this campaign does NOT require the player to move underwater, as seen in Route Kanal.
Exploration is rewarded with supplies and make sure to use adrenaline wisely!

Keep your eyes open for the Lambda symbol and the HL2 supply crates!

I'm looking forward to read your comments, reviews and watch the video's every1 uploads! :)

Dam it 2! The Director's Cut
Dam it 2! The Director's Cut

Much longer first map with a longer walk in through the forest. Cross the bridge and enter the opposite side of the Dam complex then head back across the water and in to the main complex up the elevator and to the top of the Dam for a bespoke finale.

Please set GAMEINSTRUCTOR_ENABLE 1 in console for the finale, there is some simple but vital logic to learn for the first couple goes.

Thanks to:

- Estoopi and friends - promod versus testing

Beldurra 2
Beldurra 2

The infection has left more than a wake of dead in Beldurra. Something big is living there now, and it brings down the Survivors' chopper as they attempt to fly over. Survivors will make their way from the wilderness, through the city, and finally to an all-original boss battle finale.

Beldurra 2 emphasizes an already-present arcade element while encouraging teamwork to accomplish tasks (often with multiple solutions) to proceed. There are more common infected and fewer SI, among other changes.

Features original textures, sounds, music and gameplay mechanics (lockpicking, building stations, etc.)

Enabling the Instructor is recommended.

  10/03/2013Version: 2 (complete) By: SaveYourNeighbors (2)Views: 78926 (5/5 maps)

Beldurra consists of 3 chapters that take the survivors through the already-ruined city of Beldurra and ultimately downriver to a salvage compound. Equipment and obstacles are determined in real time, both to keep players alert and to make replaying levels more fun.

Features custom textures and an original end-credits score.
Beldurra is released under Creative Commons License BY-NC-ND

Special thanks to: NowOrTrevor and Sean for textures, Borkjop for ideas and assets, Chainsaws Ahoy and everyone who helped playtest, and Valve Software for an amazing core game and making the development tools available.

Beldurra is my first Hammer project.

SaltHell Park
SaltHell Park

Set in the Victorian Saltwell Park (a real park in Gateshead, UK), survivors need to navigate through it and reach the safety of the rescue vehicle. The park has been used by the military as a secure evacuation centre before being overrun by the zombie horde.

There are two hidden gnome chompskis on maps 1 and 2 and three on maps 3 and 4. Find and shoot each one for easter eggs, rewards or punishments. (Gnome decals indicate a nearby gnome; shoot the gnomes, not the decals).

Play with Game Instructor on.

v3.0: Includes massive optimisation and greatly improved FPS rates, polish and bug fixes.

Skipping Class is my first Left 4 Dead 2 project; it's a short 2-map backtracking campaign, including custom textures and custom voice over. Patch 1.4 has been released with minor gameplay improvements and a better visual appearance.
Make sure to enable Game Instructor when playing this campaign for the first time!
A longer sequel is already on the way... :) Have fun playing!

The survivor crashed with a helicopter near an abandoned school at early morning. Trying to find a way out of town, they realize they need gas for the rescue vehicle. Searching for it, they start to go through an early infected city ...

  05/08/2013Version: 1.1 (complete) By: schayk91 aka |NFG|Angerfist (4)Views: 75846 (6/6 maps)

This is the first level of a theoretical 4 level campaign i am planning. This is the opening level, where the gang have crashed their car up a hill path while fleeing the zombie hoard. One of them knows of a campsite nearby, and the gang head to it in search of supplies and help.

The Future is here. And it's not pretty. And it won't end well for our survivors.
