Doom 4 has apparently been in development for a while, but nothing has been shown off yet. However it's apparently coming
So Doom 3 IMO had some really scary parts, however it felt much more like a modern corridor shooter than what the original Doom had with its level design.
My main wish is that it keeps to horror, but really make the level design less linear and more open, with less objectives and just more surviving trying to escape any way necessary.
Do you want a Doom 4? If so what do you want to see? If not do you feel the series is too old and needs to be forgotten about? Why no to Doom 4?
