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!

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.

It's great that the latest MMod patches have fixed the Hunter encounter. Unfortunately there's another issue predating the most recent patches which is this awful red tint all around everything looks red and crummy. Corpses that are supposed to be burnt black look like a sort of red-pink clay. Turning off MMod saturation only ameliorates the problem very slightly it doesn't address the real issue.

This problem is not occurring in ep2 with MMod.

EDIT: weirdest fix ever. I toggled 'color correction'-which is under Options-Video-Advanced-and this maybe with (trying and failing) to check the box for Bloom seems to have fixed it. Weirdest part is that turning color correction back on does not recapitulate the problem. It still looks okay burnt corpses are largely black. I don't even think I like the color correction why is it even an option!?

Can someone please help? I've tried everything and can't figure out how to work this. I got the missing background image thing, found a way to fix that, but now every time it gets past the initial startup image it says "engine error".

Please help!

Edit: It says "could not load library client"

Literally tried every single way to run this mod and it does not work. And yes I have all 3 Half-Life 2 games and SDK 2006-2013. What trash!

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.
