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!

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

Not too bad, this mod was pretty well made. I didn't care for the hazy weather that was everywhere, including inside buildings, which made me feel like I was playing inside a smoke-filled bar. The only issue I had was the part in the train station where you have to pass through a force field where prisoner canisters are passing through; the force field was not able to be disabled in anyway and I was forced to noclip to proceed.

You have to stop both canistes when they are in the field. Then You will be able to pass between them.

There were two buttons which stopped and started each of the prisoner canisters. If you stopped both prison canisters midway through the force field, it would open up a hole in the force field.

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.
