Map Labs is an ongoing anthology of Half-Life 2/Source Engine levels, all designed for the various Map Labs mapping challenges. Currently touting hundreds of maps across a multitude of competitions, we're just getting started.

  • Every qualified entry sees a release through this page until the Steam version goes live. Once on Steam, all entries will receive an achievement for completion! This is retroactive, so maps before the Steam release will still have achievements.
  • Enhanced engine base with numerous code fixes, constantly being built upon and improved.
  • New enemies, such as the terrifying Lost Souls and Shadow Walkers - with more to come down the line.
  • Additional weapons not available in stock Half-Life 2, such as the Stunstick, Flaregun, and S.L.A.M.
  • Community-contributed enhanced content, from new music to improved assets.
  • Additional tools for mappers, such as viewmodel overrides and increased projected texture limits.

Map Labs is a continuous and ever-growing series. Map Labs currently includes:

  • Map Labs #1 - Halloween Horror with 7 entries
  • Test Tube #1 - One Room with 14 entries
  • Map Labs #2 - Episode One with 7 entries

Alas, season one of Map Labs has come to a close with Test Tube #5. With the past competitions asking mappers to create advanced maps, we thought we'd scale this one back to just dev textures.


Orange and gray squares and blocky geometry may not be the most impressive thing to look at, but it's an essential step in creating the remarkable levels you see throughout Source games. But what if there was an entire theme about just that step? What's what we decided to end Season One of Map Labs with; Blockout! Mappers had three- err, four days to create the most impressive blocky geometry map they could. This competition received 13 entries and 3 bonus entries, totaling 16 brand new Half-Life maps with a whole lot of orange!

Third place was taken by Skorly, with "City of Confusion". This map is visually stunning, starting with one of the most impressive vistas we've seen in Map Labs to date. And it's made of like, three textures. With a surprising amount of detail squeezed out of the brushwork, this map sends players into a strange city infested with combine to save someone dear to them.


"twisted_gravitea_" by Jakob // Tea steals second place with its twisted gravitea. I mean gravity. Using some clever mapping, this level sends players on a stroll across the floors, walls, ceilings, and in-betweens of this abstract, Portal-like course. What it may lack in depth, it makes up for in creativity and ingenuity.


First place goes to "Desolation" by iiboharz and Jackathan. This map has everything. Great visuals, fun combat, some light platforming, easter egg dolls that catch everything on fire, tight level design. It's all-around a great map and absolutely deserves winning.



As always, here's a score sheet so you can see how every map in the competition was scored. If you'd like to read or share reviews of entries, join our Discord community! We have a dedicated channel for it.



We've made it! 10 competitions in a single year, with some off-season competitions for some extra flavor. The team is taking September off, and we've canceled the previously-scheduled Wrap-Up to give everyone some time to cool down before we come back for Season Two on the 4th of October - where the sixth Map Lab competition will be judged by Tyler McVicker from Valve News Network!

Thank you to everyone who joined in on Season One, whether you were an entrant, player, PCGamer journalist, streamer, YouTuber, or just someone in our Discord who seemingly never plays any of the competitions but is just as excited as everyone else. You've all made this a great first year, and we can't wait to deliver another.

There's something else! Moving forward, assuming everything goes over smoothly, we will no longer be releasing competitions on ModDB. There aren't any issues with ModDB, this place is great! But we're hoping to launch the Steam version of Map Labs very soon, with all of Season One with it and with Season Two being added in over time.

As always, if you're interested in joining Map Labs make sure to follow us on Twitter and join us on Discord. People who enter get a special role that turns their name green! Thanks for reading, hopefully our next article will be to announce the Steam version!

Tell me how do i edit the damage of a weapon in Half-Life 2 (not modded)?

skill.cfg file? In the hl2\cfg folder.

Technically you'll be modding the damage of the ammo the weapon uses. But they all use unique ammo types, so that's essentially same deal.

Thanks, if you dont mind could you tell me how to change the weapon sound too?

For that go to scripts\ and find the script file bearing the weapon's name. For example, scripts\weapon_357.txt. There you'll find its various sounds in a table.

The sounds used there are "script sounds", as in, they're not paths to a certain sound file, but rather they use one of the entries in the game_sounds_weapons.txt file, which lets you use randomised sound files tied to a single sound entry.

For example, the revolver uses "Weapon_357.Single" for its firing sound. You can see it in weapon_357.txt, under "single_shot" line. If you go to game_sounds_weapons.txt, you'll find that "Weapon_357.Single" entry points to two possible files, so that makes it randomly choose between two sounds, to sound less repetetive.

So, if you want to change it to another sound, you may first add it in game_sounds_weapons table. Easiest just to copy some existing one and change it accordingly.

Btw if you join the Map Labs discord, there's mapping and technical channels where you'll quickly find answers for anything like this.

Some maps utilize Map Labs-specific features that won't work in MMod, but most of the maps should work!

I had this idea by downloading all the Map Labs series to make a simple full game, instead of putting everything in the "sourcemods" folder, I put in the "sourcemods/maplabs/*" to play one by one of each series

It's not a competition my dude, but it IS something we've planned since before we even started. Give it a shot when it releases!
