The moment has come! We have finally finished Mission Improbable!

Posted by insta on Jul 29th, 2012

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.

Mission Improbable 1 - Broken floorMission Improbable 2 - Rebel base

"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.

Mission Improbable 3 - TunnelMission Improbable 3 - Shaft

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!

Well that sucks. I gotta hit the sack, being an old man and all. I guess the sooner I fall asleep the sooner I shall wake and get to play. That's got to be a law of physics right? Maybe one of those laws written in fine print, one that nobody really takes notice of. Got to be...

Installed through desura and it was exactly the same and ended at the same place. I guess that this is not a desura updat.

I played it through whilst recording with fraps...
realised after I played through the whole thing that I forgot to record sound as well. *facepalm*

I glitched the elevator after the hunter sequence, it mustn't have a clip surrounding it properly because I managed to jump through it when it was going up. I also managed to get stuck in the clip that closes off the elevator on the edge of the initial radio tower station when I played MI2, so I'm not sure if that is re-occurring.
Hilarious mod, I wasn't expecting the flowers when I first picked one up. And that pigeon... and man, the mattress billboard was an amazing edition. Also, christ Magnus knows how to open doors!
I loved it.

I totally missed that mattress billboard joke! I was like "Look ma! I'm a headcrab!" in my Let's Play series!

Sad to hear about your audio glitch. I hope the glitch won't happen again with your copy of FRAPS.

Can you make a .rar or .zip archive version? I has problems with installation, I has steam but this installer don't want to install this mod( 4put.ru ), and why I can't select installation directory?

Rick_D Jul 31 2012 replied:

It finds your steam directory based on registry values, perhaps you manually moved your steam folders without reinstalling?
Anyway, there is a 7z archive on PlanetPhillip (drop by his site and say thanks!), you can also go here for links:

I think everything in this mod is awesome! So many details and amazing map designs. I liked the shield and the missiles, nicely done!

The ending was great! Rocket-launchers don't work very well with trash :P
