Before reading on, please click here so that you can start your download! It's been a long journey to finish this project. With the first map being made and released back in 2009 and the second map being released in 2010, it has taken another 2 years for the project to be completely wrapped up.

Initially I intended to just create the final map and do some script and minor graphical upgrades to the previous levels, but while having a beer with Rick one day he suggested that he could help me out with some art to make the levels even more awesome.

"It'll only take like 2 months" he said "we'll make some new rocks and stuff, it'll be easy!" That was back in December. From then until now we've done almost complete rebuilds of the old levels, replaced almost all Half-Life 2 content with original art, and created 2 new levels as well! We have around 300 new textures being used in the mod, along with 300 new models.

It's a great feeling to finally be able to release Mission Improbable. It has been a lot of late nights and long hours to get it done, and we sincerely hope you'll enjoy playing it. In case your download hasn't finished quite yet, then you can take a look at the launch trailer below.


The download is STILL not done? Then check out this videoreview that Valvetime.net did! They reviewed a pre-release version of the mod, and awarded it an A-!


By now I hope the download is done. Again, we hope you like it, now we will go get some well-deserved rest!

Request
Could anyone please tell me the correct sequence to download and play Mission Improbable. I have no idea what Synergy is or what patches to install and in what order? In WIN10 I get the start up music and a picture of a lighthouse and then it all just goes away? Is there a vpk like with other mods?

Love the mod, however having played it twice now I seem to have found an issue with the MMod version. After the outdoor bit with the sniper, the elevator call button works but once the elevator reaches ground level only the inner door opens. I have to noclip into the elevator to proceed. Other than that this mod is fantastic, I'd literally give it a 10/10. Good work.

As a man who is not a huge fan of half life 2 vanilla in general
I must say the Mmod's new and improved features with this mod's absolutely stunning map design makes a great experience

Also I've heard it was a bug
but the red tint really suits the mod well

I think I've seen the pink hue in a video but in my game it's way way too strong. I have MMod and an NVidia card. Maybe one of them has a setting that's mucking it up?

It was an option that had nothing to do with MMod or my GPU.
