Mission Improbable is a singleplayer mod for Half-Life 2: Episode 2. In it, Gordon Freeman is tasked with re-activating a Resistance listening post. From there, things quickly escalate.

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.


There is much to explore and discover in this mod. A very Half-Life-2-centric mod with plenty of combat and storytelling. Beautiful vistas throughout, epic brushwork, and plenty of custom content. Especially impressive final chapter.


The level design is utterly superb, and reminds me of something like Minerva: Metastasis. I also applaud you for getting Stephen Hawking, the brightest mind of this and the last century, to make a cameo appearance. Are you thinking of making a sequel?

I think it was nicely done! I had trouble understanding that I needed to get the car out of the garage, but other than that the map was challenging and super fun! (love the cave at the beginning)

Very well done. Loved the attention to detail. Fun firefights. Challenging puzzles.

Nice job, just wish I would have found that third flower. I only have 2 of 3.

Closest to Episode 3 as you're gonna get. You perfectly managed to capture the look and feel of half-life. It just feels like Valve made it. Which says a lot. This is the quality a game should have let alone a mod. Another person that should be hired by Valve :D

This is the first mod I've downloaded from ModdB, and holy **** is it good! Very professionally done! If this weren't in essence, Half-Life 2, this could pass for a believable single-player campaign of a completely different game. I absolutely LOVED the outdoor enviroments. Those are what made the campaign so believable for me.

Very well done, the combat and the story are fantasic, the environment is superb, it was just like playing a extra two levels from half-life 2, 10/10 simply fantasic

Very nice mapping, great gameplay, great physics, good story, nice extras you wouldnt find in half life, like the start when you come in on the boat. Great work! Keep it up, 10/10!
