Using the Source SDK Base 2007, Ground Complex is an action FPS mod taking place in a futurist and science fiction world. It is developed by only one modder, Bioko. You have been sent alone, to a warm desert planet for a commando mission of high risk. Your goal, as an elite soldier, is to infiltrate the abandoned human complex to perform vital maintenance tasks and to recover precious scientific research facility data. From the warm desert to the depths of the complex, you will blow up everything that blocks your way, like doors or walls, but mostly aliens. You will then be extracted from the planet by a space ship !


Only SOURCE SDK BASE 2007 is required to play this mod, which you can download for free on Steam !

Don't forget to rate the mod after you played it !

It is now more than a month that the full mod is available to download. Despite all my attention and my tests, there was some bugs and gameplay problems which was still left, and since the release of the mod, I did my best to fix it. Today, even if some minor bugs may still occur the mod is mostly free from errors.

While the main campaign is completed, I still have many maps and content on my computer that I had decided to cut during the development of the mod because I knew it would be taking to me too much time to implement it. However, now that I am done with the main campaign, I can try to finish this cut content and to add it to the mod as a "Secondary Campaign" in order to extend the gaming experience and the life time of the mod, so that it could reach about two hours of playing ! I shall post some screenshots of the work in progress soon.

Else, the mod is now available and supported on Desura, so if you have this platform installed you can directly install and play my mod !

Thank you for reading this ! Remember that if you enjoyed the mod, don't hesitate to rate it !

It's not bad, the mass spawn of antlions does get extremely fustrating though, and I have no idea what to do during the plug part. I found every single plug and did what the commander told me to but the button does not do anything. Idk if its a glitch but it definitely put a sour taste in my mouth. 6/10

I've ceased working on this mod because I am the target of very childish french modders who are having fun creating multiple accounts to lower the community rating for the only purpose of annoying me.

Funny fact : I'm also french

Forgot to say, I'm downloading this now. I'll be checking it out later tonight when I put the kids to bed.

Thanks for all your hard work! I know how tough modding a game is let alone creating a totally new game from the source.

Don't let some little twats stop you from doing something you love to do.

Let your mod do the talking, no matter what they do they can't stop people from enjoying it!

What mods have they made themselves? I'd love to compare your work to theirs and see who's is better...

Should have been called Head-bob the game. Not too much indication of where to go or what to do. When there is text telling you what's going on your getting attacked but endless swarms of antlions so you can't really read it.
