Well, it looks like Id Software and Bethesda have learned their lesson in Doom: The Dark Ages. Whether you’re playing through the more straightforward levels or exploring the well-put-together open-ended areas, the game will throw up a warning whenever you’re about to cross a threshold and leave an area.

In my review of The Ancient Gods DLC, I suggested that the only way to move forward for the series would be to take it through yet another total reinvention - and that’s exactly what id Software has done with Doom: The Dark Ages.
