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!

Simply brilliant. The detail in the environments is incomprehensible, astounding, and epic. You all deserve a giant bear hug from GabeN and a lot more. The only problem is, it's short. Waaaaay too short. Seriously, I want like fifteen hours of this stuff. What I think you should do next is re-make HL2, EP1 and EP2's levels using your enhanced textures and effects and whatnot. Half-Life 2 needs and deserves environments as detailed as these. Just a suggestion.

Anyway, great work, guys.

Go and check out FakeFactory Cinematic Mod for that, though nothing to do with the creator of MI.

Do you mean, like the regular Cinematic Mod (http://cinematicmod.com/index.php)? Or do you mean a special unofficial version you're making outside of FakeFactory? Please send me a link, I feel like an idiot.

Some of the prettiest level design I've ever seen. Worth playing just for that. But a great mod as well.

It isn't hard to see why this mod is so highly rated, once you play it.

It's like an Expansion Pack for HL2. And it's not one of those cheap Mods, this campaign is so good it could've been in the original game.
