Mission Improbable is an episodic single-player mod series for Half-Life 2: Episode Two, designed by Magnar “Insta” Jenssen, a professional game developer, who’s also the creator of two splendid custom-made multiplayer levels, which were actually introduced as official maps, into the Valve games in question: DOD_Palermo for Day of Defeat: Source, and Arena_Offblast for Team Fortress 2.

Shortly after releasing Part 2 of MI back in mid-2010, Magnar took an extended hiatus from working on Part 3, and released the incredible Whoopservatory, also for HL2: EP2, in mid-2011. But now, he is back, he is rested, and with the help of Rick Underhill, he has brought us the full Mission Improbable mod release, featuring all-new redesigned levels for all of Parts 1 and 2, as well as the long-awaited Part 3!
