Valve is now offering mod makers the opportunity to sell their work on the Steam Workshop, allowing community content creators to earn an income from third-party mods, items and maps.

The Half-Life series can be quite glum at times, especially with no resolution in sight for the series. Good thing we have the modding community to deliver us some light-heartedness. Here are fourteen off-the-wall mods hand-picked to help relieve those Episode 2 cliffhanger blues.

For over a decade, PlanetPhillip.com has been a pillar of the Half-Life community, hosting the widest collection of single-player maps and mods available. Yesterday however, the site shut its proverbial doors for the last time…

So it’s been a little too long since our last instalment of In Development. Let’s rectify that, shall we?

The popular “XboxAhoy” YouTube channel, which is a member of the Machinima.com gaming network, just uploaded an excellent retrospective video analysis that explores Valve’s success with the original Half-Life.

Written by Stuart Brown, the video analysis highlights the early influences of Half-Life, such as Quake as well as the affect that Half-Life’s release had upon the FPS in genre, including the modding scene as well as Valve’s later developments with Team Fortress, Steam and the Source engine.

If you have a spare 20 minuets, it’s well worth a watch!

This tutorial will show you how to create custom textures for use in creating maps for the Source engine. The process is also the same for creating textures for models, sprays, mods and essentially any image data within any Source game.

“One 4 Nine” is a community created Left 4 Dead campaign made by Kevin “keved” Edwards.

It was originally released for Left 4 Dead in 2010, however it received a significant update in July this year.

If you followed Part One of this guide, you should have some idea about the Source engine’s basic lighting capabilities. Now let’s go a step further to look at the more advanced techniques that the engine has to offer, including the extra capabilities of Portal 2, CS:GO and Dota 2.

Thanks to our previous Source tutorials you may have created an excellent map, but without lighting your players are going to feel left in the dark.

There are a range of different entities responsible for providing illumination in the Source engine, and the number and complexity of options open to you depends on which game you are mapping for. This guide will begin with basic lighting for Half-Life 2 and other Source 2007 games, before shedding some light on more complicated techniques.

If you followed our first Source SDK tutorial, you should have gotten to grips with the basic features of Hammer: you can use brushes to create rooms and corridors, change textures and place props. Your level is still mostly lifeless though, so it’s time to use Triggers to make things happen.
