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.

v1.1
Half life 2: Deep Down (Steampipe Version) 1.1

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.

Very nice, well done mod.
Alex has an interesting manner of getting to the passenger seat of the car; instead of walking around to the right side, she just...climbs over the top of the driver.
But the programming is well done; she follows so well that when she eventually stopped I thought I might have encountered a glitch. But she also stays out of the way and avoids getting killed in fights where I am OK, but could likely not protect her well enough. I have played many games where my AI buddy insists on charging into the bad guys guns blazing, making it unnecessarily difficult to keep them alive.
The idea of taking the car down into the mine is novel, to say the least. +

Just downloaded the mod, placed under the sourcemods folder, restarted Steam, it shows. Great! I had enabled the "betas" with HL2EP2 and it is marked as "[beta]". Launched the mod... I see Half Life 2 Episode 2 turn green for a few seconds, then nothing happens, as if the game crashed.

What next?

Play the Steam version?
sorry I don't have a better answer. This mod is designed to work with Steam.
