Early trailers of the Mod can be seen here, these trailers showcase areas created by both designers.

Note.png Note: Please note these trailers were made whilst the project was in early development. Thanks to GameStand for hosting the mod and trailers.


The mod began over a year and a half before release after some brainstorming between the two creators, Henley Bailey and Richard Acherki. Different ideas for plot, character development and settings were discussed until they both agreed on the Rock 24 concept.

The mod went through several stages of redesigning, before the firm decision was made on the plot and overall feel and look. At this point proper development began, areas were planned, set pieces discussed and work allocated between the two developers. After about one year's work, Rock 24 is finally complete and available for download.


Henley Bailey and Richard Acherki previously worked at Eidos Interactive but have since moved on to other things. Level design has always been a passion for both the creators and after some tinkering with the source engine the decision was made to create a full Single Player experience using it.

Rock 24 is both designer's first project and also their first mod. Their understanding of the Valve Hammer editor and it's processes were almost exclusively learned during development. They also feel the skills they have gained will allow for quicker development time and more advanced design and implementation in future. If you are interested in hiring either or both designers, please get in touch.

Known issues

There are a few known issues, these may be fixed and a new version uploaded if a high volume of users report these issues.

  • The Setup.exe file sometimes will not install requiring the user to obtain a .zip version that is available for download here.

( zip file )

  • User may experience a crash between Overboard (first map) and Wakeup Call (second map). If this occurs the user should manually load the second section by selecting it in the chapters on the front end menu. No game play is missed as Wakeup Call being loaded is the actual issue.
  • Richard's voice will overlay if the user triggers more than one Faceposer scene at a time, this can be done by running through the level as fast as possible.
  • Richard may become stuck between Breakout (Third Map) and Surfacing (Fourth Map) if the user runs through the load section before Richard.
  • Richard's voice may repeat in Breakout after using a retinal scanner.
  • Laura's voice can be heard throughout the Surfacing level, the audio is removed in the .zip version of the mod to halt spontaneous acts of self harm through frustration.
  • The player can press a button through the bars in Breakout, breaking future scripting with Richard and making it impossible to progress.
  • Starting the game from "Breakout" results in the player having no HEV suit (there is a crowbar situated under the first video screen).

Manual install

  1. Download setup.exe
  2. Extract files... using 7zip with fullpath names
  3. Move the Rock 24 directory inside $_OUTDIR to Steam\steamapps\SourceMods
  4. Take a copy of rock24_bg_widescreen.vtf and rename it rock24_bg.vtf in Steam\steamapps\SourceMods\Rock 24\materials\console if you get the "can't find background image" error.
  5. Restart or start steam and you will find Rock 24 in games.


Some testimonials of some of the people who have played Rock 24:

midkay: Verdict: The best all-new-storyline HL2SP mod I've ever played - great gameplay, visuals, flow and design. Something for everyone. Score: 10/10

Crawler: Just finished the mod, and I have to say I'm impressed. It was MUCH more than what I expected it to be. Really, with a little more fine tuning, it could have been part of the HL2 Story. The voice acting was really good, and some of the "jokes" (at least I think they were jokes and not part of the British accent...) were funny and added depth to the characters and story. Biggest surprise was that it WASN'T like an escort mission. Richard was good enough to protect himself and help me out with some of the combines. Overall, it was a great experience, very well made, and both blokes get a tip of my hat (beanie? ... w/e..).

122334: Excellent mod, I had a blast playing it, the elevator part was totally epic, I felt like I was in a movie. Well done!

hen7: That. Was. F*cking. Awesome. The best mod i ever played. ROFL PSPs

lillbrorsan: Just played the mod and i gotta tell you it is one of the best well made single player hl2 mods out there right now, I really enjoyed playing through it.

nebukadnezar: awesome job guys! this is easily the best hl2-mod I've played so far. +great Faceposer-work.

RickiusMaximus: There's some really nice puzzle rooms in here, and a good story line all round. The method of breaking out of your cell is a nice use of the engine. My only bugbear is the first zombie in the vent is way to close to the loading zone, and I retreated right back into it- since it fades in I was stuck in the dark fighting a Zombie not to mention having to wait for the privilege!

LampShade LOL, just an awesome and brilliant game.... I love how you used FL studio so well to make the music (amazing).... anyways, thanks for yet another contribution to the mod community, good stuff and keep up the great work.

lillesnus really nice game, especially sine I am waiting like hell on HL2: Episode Two. extremely nice done. keep up the good work. greetings from an Norwegian enthusiast. :D

GFreeman35 This is good, i really love it. But the only problem i am having is that my sound isn't working, but other than that, it's awesome.
