City 12 is about to be free once more.

  • The resistance is operating openly and is rapidly regaining influence.
  • The Civil Protection is increasingly corrupt.
  • Anti-combine television broadcasts are tolerated.

To avoid a full uprising, the Combine has agreed to formally restore human rights in City 12 and allow limited human self-governing. The treaty will be signed in just a few days. There's doubt the treaty will actually be signed. To put more pressure on the Combine, the resistance is about to assault key civil protection stations in the downtown area. Freeman unexpectedly arrives in City 12. Unsure what to do with him, they ask him to lead the assault on Sector V.

Altered Transmission is a single player mod for Half-Life 2: Episode Two. You need to install Source SDK Base 2013 Singleplayer from Steam's Tools tab as well as Half-Life 2: Episode Two. See README.txt for installation instructions. City 12 is loosely based on Århus, Denmark and many locations are based on the real world.

This is Demo 10, a development snapshot of Altered Transmission. The mod is not finished and probably never will be as I was too ambitious and it is too much work realizing my vision for it. Nonetheless, with a strong focus on gameplay, all the neccesary maps have been made and the mod is fully playable from start to finish. There's no voice acting, but the story is told through subtle environment details. A few maps are still have rough graphics, but they are all playable. Please ignore any obviously unfinished aspects of the mod.

This is as gameplay test. I'd really like to know what you think of it. There's lots of ways you can give me feedback:

  • Leave a review in the comments.
  • Add sortie as friend on Steam and interactively tell me while you play.
  • Record demo files in the engine that I can play back.
  • Publish a Let's Play of the mod.

Good evening,

I've just uploaded Demo 10 of Altered Transmission. This is a fully playable gameplay test of my mod still in development. This release contains all 18 gameplay maps, while lacking 2 story maps of rebel bases. This is the first release to fully connect the mod together. The graphics and gameplay has been considerably improved. This is definitely the best release to date. I hope you'll enjoy it too.

Altered Transmission - Demo 10

Demo 10 was originally scheduled for release in June 2009. After learning some harsh lessons about how not to do release engineering, and my attention being better used elsewhere, I never made the release. That was unfortunate as I had a lot of great unreleased content. It is with much pride and satisfaction of my personal pride that the release was delayed by no more than six years.

Chapter 1: Prewaves Chapter 1: Prewaves

I put up a 7z of the mod directory as a moddb download. There's an advertisement as you download, but moddb doesn't seem to do anything nasty to downloads so that's great. If you'd much prefer downloading it elsewhere, let me know. I'm not sure how mods are best released these days.

Chapter 1: Prewaves Chapter 1: Prewaves

As always, the mod is perfectly playable as I put gameplay and level design design first. There's no voice acting yet, but lots of implicit story telling. Please provide me with your feedback so I can improve the mod, or just feel the appreciation. I put a lot of work into this.

I hope you enjoy it!

Impressing one-man mod. While a few parts are a bit rough and unfinished (as he points out) the ones that are done are mostly incredibly detailed and look professional. Difficulty is occasionally insanely high, although that may be a good thing after all.

I got to some part were there is a barricade with two turrets manning it and a scaffold nearby and a ladder out of reach and I couldn't figure out what to do so I gave up. Does anybody know what to do?

You have to knock down a turret using gunfire/explosives. That was trained in an earlier map. The gate opens once you knock down a single one. I've made a note to think about what happens if the player doesn't solve it.

It's alive! And it's good. So, who controlled City-12? Or would it be mystery forever?

Thanks! Demo 10 contains enough clues to figure it out but it is never directly said.

played Demo 10 and enjoyed it A LOT!

Thank you for this fine piece of work.
Looking forward to the finished product with more zombies, Combine and such.
Really liked the aid of the resistance throughout the maps and levels.
I'm giving your Demo 10 a 9/10!
