Yes at this point park the hovercraft somewhere and climb above the tunnels by a ladder and you will see a washing machine, push it till it drops down, then go down again and pull the lever. That will do the trick!!
It only needs that washing machine!
cant you see thats fake? But in the other hand as you were saying that the Dog will be pulling the chopper out is quite....not so ingenious to Valve.....
Remember as one of our friends here mentioned that Valve will surprise us again!!
I should agree with you !! As we saw over a few leakages of ep3 gameplays the game will begin first at white forest then they will somehow get the chopper fixed and then they will fly to the arctic base!!
