Id Software has been working on the latest Doom game for a long time. A very long time. It's had some false starts and some bumpy stretches, but the game is getting ever closer to becoming a real thing that people can actually play.
The first early gameplay footage was revealed exclusively to QuakeCon attendees last July. It was brutal in all the ways old-school Doom fans will like, but nobody outside of that Hilton Anatole ballroom has had a chance to see it (somewhat amazingly, it never leaked). That changes at E3 next month, where Id Software and Bethesda will unveil what the game looks like for a worldwide audience. So mark your calendar for Sunday, June 14 at 9 p.m. (central time).
I'm eager to see how much the game has progressed since I saw it last year, but you can re-read my live-tweeting of that original demo in the Storify embed below.
