Half-Life 2 The Road to Abyss

Description
You find yourself arriving at some sort of Combine facility. You are taken to a room where you are attacked. Next thing you know you wake up in a bin, presumably assumed dead.
Wasting no time, you begin to explore and you find two identical rebel twins who tell you exactly what you need to do, it's just they tell you in Russian!
As in most mods, you don't really need to hear what they say, just do what you do best; find and kill Combine. And so, starts your journey to Abyss!
