Drugod (our hero) heads to Romero Games' offices for a job interview with John Romero himself, but things will not go as our hero hopes...
CV.wad contains a unique map, I recommend to play cv.wad with Gzdoom although it could also be played with Zandronum, it can also be played in cooperative although it was thought to be played in single player.
It is compatible with smooth doom, brutal doom, project brutality and derivatives.
To complete the wad there are different ways to do it, depending on how you behave with John.
I hope you enjoy it.
