The Revenge mod for Half-Life 2

One more mod, but this is different from others. But how? You'll know when Beta version releases. You say "How long should we wait?". OK, I'll tell you a secret
The mod will tell a story to you about a rebel, who lost his brother in the battle with the combines for his home town.  After hearing on the radio a speech of a man, who commands the forces of alliance, about that everyone who resist will be pitilessly destroyed, he placed himself in a mission - "find the bastard" kill him and tear the alliance into pieces, take a vengeance for the close people the combine killed, first of all - for his brother.  He understood that it was crazy and most likely he would die, but he solidly decided - to take do it, to at least attempt to reach to the staff of alliance and to destroy as much combines as possible.  And of course Mr. G is there, since he is interested in destroying the alliance and the citadel in City 17.  Although this task seems to be for Doctor Freeman, but still G-Man decided otherwise.  The main hero "wakes up" in a train, which holds course to City 21. From here the control of the hero and his fate passes under your control. Why in the train? It is difficult to say. Probably for the same reason, that every main hero in HL begins in the train or near it (but not in the First Episode).  It would seem simple task, nothing special. You may ask, "So what's the difference from other mods?" Here are some of them:
1)You decide... In this mod's levels you will frequently encounter obstacles and several (2 or more) methods to overcome them. It is possible to burst open, while it is possible to quietly go around, climb over, swim across or to jump over. Whatever you face, you will have an exit, or even two exits. Sometimes it will seem impossible, but it's not so. You will just have to work your brains. =)
2)Long levels... In the levels where you must go from a base to base will be very long. You will have to go by foot to other bases. "Vehicles?" Vehicles don't walk!! Everywhere on the streets will be combines. "The subway?" The subway also doesn't work, or maybe...
3)Hard situations... You will fall in many hard situations, such that are not in other mods and the original HL2. For example...no, no examples for now. We don't want others to steal our ideas :)
4)Videos after each level...
After you beat a level you will see an inside the game video, which will show you the continuation of the storyline. We never saw another mod with this kind of feature
