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!

Can't play it, I get this error message:

"can't find background image materials/console/startup_loading.vtf"

EDIT: Ok, I managed to fix it, but now I get this error message:

"RaiseJSException: Method call failed: Installs.OpenInstallWizard call had invalid argument (arg 0): is_array: true array_values { double_value: 1.7137182221321615e+19 }"

Anyone know how to fix it?

Unfortunately, the installers don't work. Seems the last few posts are experiencing this too. IT would be nice to play and have an updated installer that actually works. I would love to try this game.

Hi there - this plan didn't work?
"
Read txt from last update Moddb.com
1. Install files.
2. Install SDK-2013, with beta
Ensure that you have Source SDK Base 2013 Singleplayer installed and configured to use the latest beta, "incoming".
If not set:
- Right-click on Source SDK Base 2013 Singleplayer.
- Go to the "Betas" tab.
- Change "Select the beta you would opt into" option to "incoming"
"

Maybe they fixed it, because I had no problem installing the mod. The only thing I needed was the 2015 patch to make it work.
