Mission Improbable

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.

A Resistance listening post suddenly goes off-air and you are sent in to find out what happened to the original support crew and get the station back online. Your journey begins as a rowing boat coasts towards the landing point. Who knows what you will encounter, both on the way up to the tower and on your way down? After that who knows where you will end up, or what you will have to do?
