Firmly sticking to the Half Life 2 formula, Deep Down is a new entry in the story of Alyx and Gordon as they continue the hunt for Combine Advisors in the area surrounding White Forest.

Combine Forces, Zombies and Antlions lay between them and the brooding menace deep below the earth that will test both their skills further than ever before.

If you miss the Half Life 2 formula and are tired of waiting patiently for Episode 3 then this mod is for you. Featuring new gameplay elements, fiendish puzzles and blistering action, Deep Down will provide your Half Life 2 fix (well some of it at least).

Finally made it over the finish line after a drama filled few weeks of technical issues with Source SDK. Deep Down is my attempt to recreate the game-play and style of Episode 2. I had no idea it would be so challenging. I must have lost days of my life trawling through audio files trying to find just the right phrase for each moment. Someone should seriously catalog this stuff.

In this mod you'll find 5 maps filled with combat and puzzles and hopefully some things you haven't seen before. I'm calling this version 1.0 as I'm sure there's room for improvement.

I hope you enjoy playing this as much as I enjoyed making it.

Ooh one more thing.

There are several hidden unofficial achievements built into the mod and I'll let the community at large figure them out.

The mod rewards curiosity so keep your eyes peeled and explore all you can...

Hey... you should be able to download the mod. then unzip the folder into the Sourcemods folder on your c drive.
you should find it in a folder similar to: C:\Program Files (x86)\Steam\SteamApps\sourcemods

Once installed. Shut down steam and restart it and you should then see the mod in the Steam Library...

I just finished this and I have to say that it was very well put together, nice work. :D The only problems I noticed was that a good amount of sounds were all muted for some strange reason, like the Hunter and Charger (EP2 vehicle) were totally silent past the first map, dunno why though but it's true, just odd... :/ But other than that it was very well put together and I look forward to the next part, definitely tracking this mod for future updates. ^^
