Half-Life 2 map: Drainage updated!

Now almost six years after I originally released my most succesful custom Half-Life 2 single-player adventure, Drainage, I'm going back to release a new version. Even I think it's unbelievable but I finally decided that it has to be done.

The reason for this is that Valve updated Half-Life 2 to use the Orange Box engine a few years ago that also updated the enemy AI at the same time. This change introduced a game breaking issue in the first map of Drainage rendering the whole mappack pretty much unplayable.

As this problem had already existed for a couple of year I really think that I should have dealt with it way earlier. Anyway, now it's done and I can finally feel peaceful again. Go play the map!
